because it's all templated functions.

Significant refactoring of NMF tests. The sparse tests were generally invalid
...
because NMF is not guaranteed to produce a unique decomposition. Instead, now
we test the Frobenius norm. Also, the tolerances needed to be significantly
adjusted because of the new convergence criteria in the AMF class. Lastly, the
SparseNMFRandomDiv test and SparseNMFDefaultTest have been removed because those
update rules seem to often result in NaNs when sparse matrices are used as
input.

Fix for convergence, because sometimes the residue may increase (especially with

ALS update rules).
