New description:
This patch overhauls, consolidates, fixes and expands matrix augmentation
and stacking.
Fixes:
* subdivisions of matrices are generally not preserved under these
operations, but now are
Features:
* a vector may now be supplied as a second argument across all routines
Consolidation:
* there is some standardization of variable names and techniques across
the routines
Expansion:
* augment() for dense integer matrices is uncommented and working now
Documentation:
* new features (vector argument, subdivisions) have been documented
where added
* a general upgrade in documentation would be valuable, on another
ticket
To Do:
* work to have result formed over a common ring
"general" patch adds vector argument and subdivision support to the
generic `stack()` method. Subdivision management is split out as helper
methods for use with routines in the "special" patch.
"special" patch works on routines for dense integer matrices, mod 2
matrices, and generic sparse matrices. It also moves the generic matrix
`augment()` to a better location in the source (it was left in place so
changes could be seen more readily on the "general" patch).

special.patch
