* 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
