added functions to calculate the shape and volume mismatch of compatible and non-compatible geometry reconstruction to postprocessingMath. They can be accessed using addDebugInformation
polishing, mainly in fft reconstruction.
added fftw library file and fortran file for type specification
added folder references with literature for visualization/geometry reconstruction
postprocessing: renamed name of python/f2py modul from "reconstruct" to "postprocessingMath", added some numerical operations to use for postprocessing.
