Removed debugging printf statements
For some reason, with -O0, gtest doesn’t link (needs isspace, etc).

I haven’t figured out why yet, but removing this flag at least allows
the tests to run.
changed code in Dmodules/Sparsemat.m2 to create a dense mutable matrix.

Previously, it created a sparse mutable matrix, but the code to reduce
by pivots is not written yet for sparse mutable matrices.  We need to
see if there is a performance penalty/gain.
changes to mgb interface to handle modules.

Module orders not yet in place, and not yet tested.
