e655fed4fa Replace Arc<SparsityPattern> with SparsityPattern 
After much deliberation, I have come to the conclusion that the
benefits do not really outweigh the added complexity. Even though
the added complexity is relatively minor, it makes it somewhat
more complicated to inter-op with other sparse linear algebra
libraries in the future.

6a1d12705f Remove old .get() API for CscMatrix in favor of entry API 
This essentially makes the API of CscMatrix analogous to
that of CsrMatrix.

b59c4a3216 Refactor most of Csr/CscMatrix logic into helper type CsMatrix 
Still need to update CSC API so that it mirrors CsrMatrix
in terms of get_entry and so on.

ec339f9108 Implement CSC matrix basic API 
The CSC matrix API mirrors the CSR matrix API. However, there
are subtle differences throughout (both in the available
methods and the implementation) that I believe makes any attempt
to avoid the duplicate effort futile.
