Matrix generation cleanup

Browse Source 
1. Convert a CompressedRowSparseMatrix constructor which
takes a TripletSparseMatrix as input into a factory method
which allows the input to be transposed.

2. Move the random matrix creation routine for CompressedRowSparseMatrix
from being a standalone function to a static method.

3. Add a corresponding random matrix generation static method to
TripletSparseMatrix.

4. Add a new constructor to TripletSparseMatrix, which takes as input
the row, col and values arrays.
