Added BitVector, a simple boolean array
Added BitVector, a simple boolean array
Edited AtomicProposition to make use of BitVector Edited mrmc-cpp.cpp, now comes with speed tests for some tasks Edited static_sparse_matrix.h, added a copy constructor, added template conversion functions, applied template parameters to all relevant functions/variables Removed eigen_sparse_additions.h from internal filestempestpy_adaptions
