Detailed Description

A MatrixCommitment provides a set of acceptable matrix characteristics.

Since we define the characteristics each with its own bit, a commitment is implemented as a set of masks with bits set corresponding to the acceptable characteristics.

For any handle commitment, we can calculate a "best character" for an allocation that satisfies the commitment, optionally with an initial allocation size.

Typically it is the least-restrictive actual character that satisfies the commitment. For example, if the commitment is Triangular we'll allocate a full triangular matrix, not a banded one, or a symmetric one, or for that matter an identity matrix, all of which would satisfy the commitment. The supplied sizes are used as minima – if the commitment requires a larger minimum size you'll get that. For example, if you specify 0x0 but you're committed to a Column outline, you'll get 0x1.
