!> @brief This is a library of functions for Input and Output pure Fortran data in VTK format.
!> @details It is useful for Paraview visualization tool. Even though there are many wrappers/porting of the VTK source
!> code (C++ code), there is not a Fortran one. This library is not a porting or a wrapper of the VTK code,
!> but it only an exporter/importer of the VTK data format written in pure Fortran language (standard Fortran 2003 or
!> higher) that can be used by Fortran coders (yes, there are still a lot of these brave coders...) without mixing Fortran
!> with C++ language. Fortran is still the best language for high performance computing for scientific purpose, like CFD
!> computing. It is necessary a tool to deal with VTK standard directly by Fortran code. The library was made to fill
!> this empty: it is a simple Fortran module able to export native Fortran data into VTK data format and to import VTK
!> data into a Fortran code, both in ascii and binary file format.
!>
!> The library provides an automatic way to deal with VTK data format: all the formatting processes is nested into the
!> library and users communicate with it by a simple API passing only native Fortran data (Fortran scalars and arrays).
!>
!> The library is still in developing and testing, this is first usable release, but there are not all the features of
!> the stable release (the importer is totally absent and the exporter is not complete). Surely there are a lot of bugs
!> and the programming style is not the best, but the exporters are far-complete.
!>
!> The supported VTK features are:
!> - Exporters:
!> - Legacy standard:
!> - Structured Points;
!> - Structured Grid;
!> - Unstructured Grid;
!> - Polydata (\b missing);
!> - Rectilinear Grid;
!> - Field (\b missing);

!> @libvtk can handle multiple concurrent files and it is \b thread/processor-safe (meaning that can be safely used into

!> @par VTK_Standard
!> VTK, Visualization Toolkit, is an open source software that provides a powerful framework for the computer graphic, for
!> the images processing and for 3D rendering. It is widely used in the world and so it has a very large community of users,
!> besides the Kitware (The Kitware homepage can be found here: http://public.kitware.com) company provides professional
!> support. The toolkit is written in C++ and a lot of porting/wrappers for Tcl/Tk, Java and Python are provided, unlucky
!> there aren't wrappers for Fortran.
!>
!> Because of its good features the VTK toolkit has been used to develop a large set of open source programs. For my work
!> the most important family of programs is the scientific visualization programs. A lot of high-quality scientific
!> visualization tool are available on the web but for me the best is ParaView: I think that it is one of the best
!> scientific visualization program in the world and it is open source! Paraview is based on VTK.
!> @par Paraview
!> ParaView (The ParaView homepage can be found here: http://www.paraview.org) is an open source software voted to scientific
!> visualization and able to use the power of parallel architectures. It has an architecture client-server in order to make
!> easy the remote visualization of very large set of data. Because it is based on VTK it inherits all VTK features. ParaView
!> is very useful for Computational Fluid Dynamics visualizations because it provides powerful post-processing tools, it
!> provides a very large set of importers for the most used format like Plot3D and HDF (the list is very large). It is easy to
!> extend ParaView because it supports all the scripting language supported by VTK.
!> @note All the @libvtk functions are <b>I4P integer functions</b>: the returned integer output is 0 if the function calling has
!> been completed right while it is >0 if some errors occur (the error handling is only at its embryonic phase). Therefore the
!> functions calling must be done in the following way: \n
!> @code
!> ...
!> integer(I4P):: E_IO
!> ...
!> E_IO = VTK_INI(....
!> ... @endcode
!> @libvtk programming style is based on two main principles: <em>portable kind-precision</em> of reals and integers
!> variables and <em>dynamic dispatching</em>. Using <em>dynamic dispatching</em> @libvtk has a simple API. The user calls
!> a generic procedure (VTK_INI, VTK_GEO,...) and the library, depending on the type and number of the inputs passed, calls the
!> correct internal function (i.e. VTK_GEO for R8P real type if the input passed is R8P real type). By this interface only few
!> functions are used without the necessity of calling a different function for each different input type.
!> Dynamic dispatching is based on the internal kind-precision/rank selecting convention: Fortran 90/95 standard has introduced some
!> useful functions to achieve the portability of reals and integers precision and @libvtk uses these functions to define portable
!> kind-precision; to this aim @libvtk uses IR_Precision module.

!> @version 1.1
!> @date 2013-05-23
!> @par News
!> - Added packed API and 3D(or higher) arrays for VTK_VAR_XML function: this avoids the necessity of explicit reshape of
!> multi-dimensional arrays containing saved variables in VAR callings; the following inputs are now available:
!> - scalar input:
!> - input is 1D-rank array: var[1:NC_NN];
!> - input is 3D-rank array: var[nx1:nx2,ny1:ny2,nz1:nz2];
!> - vectorial inputs:
!> - inputs are 1D-rank arrays: varX[1:NC_NN],varY[1:NC_NN],varZ[1:NC_NN];
!> - inputs are 3D-rank arrays: varX[nx1:nx2,ny1:ny2,nz1:nz2],varY[nx1:nx2,ny1:ny2,nz1:nz2],varX[nx1:nx2,ny1:ny2,nz1:nz2];
!> - 3D(or higher) vectorial inputs:
!> - input is 1D-rank (packed API): var[1:N_COL,1:NC_NN];
!> - input is 3D-rank (packed API): var[1:N_COL,nx1:nx2,ny1:ny2,nz1:nz2].
!> - Added packed API and 3D arrays for VTK_GEO and VTK_GEO_XML function: this avoids the necessity of explicit reshape of
!> multi-dimensional arrays containing X, Y and Z coordinates in GEO callings; the following inputs are now available:
!> - StructuredGrid (NN is the number of grid points, n\#1-n\#2, \#x,y,z are the domain extents):
!> - 1D arrays of size NN: X[1:NN],Y[1:NN],Z[1:NN];
!> - 3D arrays of size NN: X[nx1:nx2,ny1:ny2,nz1:nz2],Y[nx1:nx2,ny1:ny2,nz1:nz2],Z[nx1:nx2,ny1:ny2,nz1:nz2];

!> - 1D arrays of size NN: X[1:NN],Y[1:NN],Z[1:NN];
!> - 1D array of size 3*NN (packed API): XYZ[1:3,1:NN].
!> - Added base64 encoding format: the output format specifier of VTK_INI_XML has been changed:
!> - output_format = 'ascii' means \b ascii data, the same as the previous version;
!> - output_format = 'binary' means \b base64 encoded data, different from the previous version where it meant appended
!> raw-binary data; base64 encoding was missing in the previous version;
!> - output_format = 'raw' means \b appended \b raw-binary data, as 'binary' of the previous version;
!> - Added support for OpenMP multi-threads framework;
!> - Correct bug affecting binary output;
!> - implement concurrent multiple files IO capability;
!> - implement FieldData tag for XML files, useful for tagging dataset with global auxiliary data, e.g. time, time step, ecc;
!> - implement Parallel (Partitioned) XML files support (.pvtu,.pvts,.pvtr);
!> - implement Driver testing program for providing practical examples of @libvtk usage;
!> - added support for parallel framework, namely OpenMP (thread-safe) and MPI (process-safe).

!> @bug <b>XML-Efficiency</b>: \n This is not properly a bug. There is an inefficiency when saving XML raw (binary) file. To write
!> raw data into XML file @libvtk uses a temporary scratch file to save binary data while saving all
!> formatting data to the final XML file. Only when all XML formatting data have been written the
!> scratch file is rewind and the binary data is saved in the final tag of XML file as \b raw
!> \b appended data. This approach is not efficient.

!> Note that this equation is different from the legacy one. The XML connectivity convention is quite different from the
!> legacy standard. As an example suppose we have a mesh composed by 2 cells, one hexahedron (8 vertices) and one pyramid with
!> square basis (5 vertices) and suppose that the basis of pyramid is constitute by a face of the hexahedron and so the two cells
!> share 4 vertices. The above equation gives \f$dc=8+5=13\f$. The connectivity vector for this mesh can be: \n
!> first cell \n
!> connect(1) = 0 identification flag of \f$1^\circ\f$ vertex of 1° cell \n
!> connect(2) = 1 identification flag of \f$2^\circ\f$ vertex of 1° cell \n
!> connect(3) = 2 identification flag of \f$3^\circ\f$ vertex of 1° cell \n
!> connect(4) = 3 identification flag of \f$4^\circ\f$ vertex of 1° cell \n
!> connect(5) = 4 identification flag of \f$5^\circ\f$ vertex of 1° cell \n
!> connect(6) = 5 identification flag of \f$6^\circ\f$ vertex of 1° cell \n
!> connect(7) = 6 identification flag of \f$7^\circ\f$ vertex of 1° cell \n
!> connect(8) = 7 identification flag of \f$8^\circ\f$ vertex of 1° cell \n
!> second cell \n
!> connect(9 ) = 0 identification flag of \f$1^\circ\f$ vertex of 2° cell \n
!> connect(10) = 1 identification flag of \f$2^\circ\f$ vertex of 2° cell \n
!> connect(11) = 2 identification flag of \f$3^\circ\f$ vertex of 2° cell \n
!> connect(12) = 3 identification flag of \f$4^\circ\f$ vertex of 2° cell \n
!> connect(13) = 8 identification flag of \f$5^\circ\f$ vertex of 2° cell \n
!> Therefore this connectivity vector convention is more simple than the legacy convention, now we must create also the
!> \em offset vector that contains the data now missing in the \em connect vector. The offset
!> vector for this mesh can be: \n
!> first cell \n
!> offset(1) = 8 => summ of nodes of \f$1^\circ\f$ cell \n
!> second cell \n
!> offset(2) = 13 => summ of nodes of \f$1^\circ\f$ and \f$2^\circ\f$ cells \n
!> The value of every cell-offset can be calculated by the following equation: \f$offset_c=\sum\limits_{i=1}^{c}{nvertex_i}\f$
!> where \f$offset_c\f$ is the value of \f$c^{th}\f$ cell and \f$nvertex_i\f$ is the number of vertices of \f$i^{th}\f$ cell.
!> The function VTK_CON_XML does not calculate the connectivity and offset vectors: it writes the connectivity and offset
!> vectors conforming the VTK-XML standard, but does not calculate them.
!> The vector variable \em cell_type must conform the VTK-XML standard (see the file VTK-Standard at the
!> Kitware homepage) that is the same of the legacy standard. It contains the
!> \em type of each cells. For the above example this vector is: \n
!> first cell \n
!> cell_type(1) = 12 hexahedron type of \f$1^\circ\f$ cell \n
!> second cell \n
!> cell_type(2) = 14 pyramid type of \f$2^\circ\f$ cell \n
