This caused inconsistencies between the shapes of Hloc and density_matrix,
since they were in the shape of n_corr_shells vs n_inequiv_shells, respectively.
In the (rare) case that one has multiple shells with different number of orbitals (e.g. p-d-systems) the old code crashed when converting GFs from the second shell as matrix dimensions were not fitting (the tmp matrix was always created for the first shell).
* adding kpts_basis, kpts, and kpt_weights to h5 dft_input
* read these properties as optional arguments in Sumk_dft.py
* change accordingly the ref h5 files for vasp converter test
* soon all converters are demanted to store those properties
* bz_weights should then be replaced by kpt_weights
* closes PR #146
* moved the plovasp C++ code to c++/triqs_dft_tools/converters/vasp
* added global header triqs_dft_tools/triqs_dft_tools.hpp
* python dir based on single cmakelist file
* registered C++ tests for plovasp
* corrected imports for py3 tests for plovasp
* corrected block order in sigma_from_file and srvo3_Gloc
* exchanged ref files for sigma_from_file, srvo3_Gloc, SrVO3.ref.h5
* moved vasp converter bash scripts from dir shells to bin dir
