Meta-issue: requests for ALP/SparseBLAS support

[anyzelman]

Since PR #11 , a proof-of-concept for a SparseBLAS interface with an implementation generated by ALP is introduced. This by far, however, does not support all standard functions. As adding new functions in the majority of cases is rather straightforward (modulo testing-- see #12 and #13 ), if you indeed have specific requests for support, please don't hesitate to request it here.

As a first request then and just to record it in the proper place: SpMM (sparse matrix dense matrix multiplication)

[anyzelman]

Update: crossref sptrsv #59. Also sptrsm was recently requested: so on the not-so-long term, it would be great to add support for SpMM, SpTrSV, and SpTrSM.

Crossref #258

Crossref #309 -- preconditioning was requested with some urgency
