TRANSFILE option provides a filename containing transformation
matrices for all ions of a projected shell.
The parser simply reads the numbers into a 2d-array which is left
for interpretation at a later stage.
If option DOSMESH is specified a projected DOS for each shell
will be output. Energy mesh parameters are given in DOSMESH as
DOSMESH = [EMIN EMAX] N_POINTS
The parameters in the brackets [] are optional. If only the number
of points is specified the energy range is taken to be the same
as the projection energy window.
The files from the original vasp-interface repository are reshuffled in
accord with the directory structure of dft_tools. Some of the directories,
such as 'test' (unit tests for the interface), 'examples' (simple examples for
the development purposes) are temporarily placed into 'python/vasp' directory
to avoid confusion with integral tests and examples of dft_tools.
