SparseArrays Interface

[rayegun]

Keep track of missing SparseArrays function(alitie)s:

• sprand
• sprandn
• Some alternative to sparse
• spzeros(?)
• spdiagm
• blockdiag
• rowvals
• nzrange
• droptol!
• dropzeros[!]
• permute[!] (not sure best way to implement this)

Closing this here. Some sort of SparseArrayCompatGB.jl will do this since the semantics of GraphBLAS and SparseArrays do not admit a common interface.
