Description

It would be great to be able to read and write to MatrixMarket formats. Is anyone working on this? If not, I could make an implementation if time allows.

Research direction
Examine existing Breeze I/O code (e.g., CSV reading/writing) to understand pattern. Implement reading and writing of Matrix Market coordinate and array formats. Look at the matrix market format specification and Breeze's dense/sparse matrix types. Consider contributing tests and documentation.
