Hierarchical block-sparse matrix library

This matrix library is developed to effeiciently perform approximate multiplication of sparse matrices with decay in shared memory.

It has been used in conjunction with the Chunk and Tasks matrix library.

The library is serial, but multiplication is parallelized with OpenMP, can be also done by means of C++17.
