Adding algorithm for caching of sparsity patterns (not enabled), #575
Added constructor to CRSSparsity, #575
Swiched to using initializer lists in Matrix<> (for efficiency)
Rearranged CRSSparsityInternal to avoid initialization confusion, #575
Concerning #575: Debugged sparsity pattern caching. Now works but segfault occurs at program closure.
