!> @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)
!> 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 (native Fortran scalar, vector
!> and matrix).
!>
!> 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;

!> @libvtk can handle multiple concurrent files, but it is not thread-safe (e.g. race conditions occur into OpenMP
!> parallel framework).
!>
!> The library is an open source project, it is distributed under the GPL v3. Anyone is interest to use, to develop or

!> @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 every different inputs type.
!> Dynamic dispatching is based on the internal kind-precision 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.
!> @author Stefano Zaghi
!> @version 1.1
!> @date 2013-03-28
!> @par News
!> - Correct bug affecting binary output;

!> - Implement Parallel (Partitioned) XML files support (.pvtu,.pvts,.pvtr);
!> - Implement Driver testing program for providing practical examples of @libvtk usage.
!> @copyright GNU Public License version 3.
!> @note The supported compilers are GNU gfortran 4.7.x (or higher) and Intel Fortran 12.x (or higher). @libvtk needs a modern
!> compiler providing support for some Fortran standard 2003 features.

!> @todo \b DocExamples: Complete the documentation of examples
!> @todo \b g95_test: Test g95 compiler
!> @bug <b>Array-Reshape</b>: \n Fortran allows automatic reshape of arrays, e.g. 2D array can be automatically (in the
!> function calling) transformed to a 1D array with the same number of element of 2D array. The use of
!> dynamic dispatching for @libvtk functions by means of generic interfaces had disable this feature:
!> dynamic dispatching use the array-shape information to detect, at compile-time,
!> the correct function to be called inside the generic interface functions. Thus automatic reshaping
!> of arrays at calling function phase is not allowed. \n
!> Instead an explicit reshape can be used by means of the Fortran built-in function \em reshape.
!> As an example considering a call to the generic function \em VTK_VAR_XML an explicit array reshape
!> could be: \n \n
!> E_IO = VTK_VAR_XML(NC_NN=nn,varname='u',var=\b reshape(u(ni1:ni2,nj1:nj2,nk1:nk2),(/nn/))) \n \n
!> where built in function \em reshape has explicitly being used in the calling to VTK_VAR_XML.
!> @bug <b>XML-Efficiency</b>: \n This is not properly a bug. There is an inefficiency when saving XML binary file. To write XML
!> binary @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 data. This approach is not
!> efficient.
!> @bug <b>Thread-Safe</b>: \n The @libvtk is not thread-safe: if used into a parallel multi-thread framework, e.g. OpenMP threads,
!> the IO operations are not safe and race conditions with unpredictable results happen.

!> Function that \b must be used when unstructured grid is used, it saves the connectivity of the unstructured gird.
!> @note The vector \b connect must follow the VTK-legacy standard. It is passed as \em assumed-shape array
!> because its dimensions is related to the mesh dimensions in a complex way. Its dimensions can be calculated by the following
!> equation: \f$dc = dc = \sum\limits_{i = 1}^{NC} {nvertex_i }\f$.
!> 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
