Matfree

This release introduces Chebyshev approximation for computing functions of (large) matrices.

This release is not backwards compatible because some functions are reorganised: the content of `slq.py` and `decomp.py` has been collected in a new `lanczos.py`. See the changelog for concrete differences, and consult the documentation for where to find which function.

The best source for instructions for using the new API are the tutorials in Matfree's online documentation.**_
