Detailed Description

Sparse matrix class.

Uses compressed row storage format, with each entry being a 3x3 GeMatrix3 matrix.

This implements the bare minimum necessary for the cloth simulation class, and is not really intended as a general purpose sparse matrix class.

Formerly, both MTL and uBLAS were used for this purpose.

• MTL: poor code clarity (looks like assembly), not easily portable to Visual C++, no support for 3x3 matrix as base element.
• uBLAS: good code clarity, easily portable, poor support for 3x3 matrix as base element, sparse matrices are second class citizens, with dense matrices getting best testing. Doesn't appear to use sparse matrices in debug mode. In the end, given maintenance issues and the difficulty of setting up Boost, this was abandoned to make the library easier to compile.
