NonminimalComplexes -- support for computing homology, ranks and SVD complexes, from a chain complex over the real numbers

Description

Some functionality here should be moved elsewhere.

Caveat

This package will be removed soon, with constantStrand functionality moved elsewhere. The undocumented features the rest of the package relied on have been removed in M2 version 1.23.
