Comment:
Patch overview:
{{{elementwise_product()}}} in {{{matrix2.pyx}}} checks inputs for proper
sizes, and coerces base rings, etc.
Then two versions of {{{_elementwise_product()}}} (in
{{{matrix_dense.pyx}}} and {{{matrix_sparse.pyx}}}) take over and do the
actual work in what should be a fairly efficient manner, given the
generality implied.
More efficient implementations are certainly possible for more specialized
classes. The intent here is to begin with a correct and general
implementation that is moderately efficient, primarily to make the
functionality available in Sage.
