In Brief:

This was used to store things like OD matrices inside matsim. Since we prefer to disaggregate such things right away into individual trips, this module was not maintained. It is not clear if maybe it should be re-surrected.

[mrieser] I recently cleaned the package up a bit, in that it no longer requires Locations (from the deprecated World concept) but just Ids, and that they work more stand-alone. Matrices are used mostly in demand modelling. As such, they are useful, but would probably need more cleanup to come up to standards.

 - think about interface Matrix to have different implementations, also backed by matrix-package (e.g. Jama, ...).
 - mostly used in initial demand modeling. MATSim needs *some* kind of matrix support for idm.
 - probably rename matrices/Matrix to odmatrices/ODMatrix to make clear it's not a general matrix impl?
