332fe8c0e4 update loading matrix market, including:
1. Several renamings
2. removed unnecessary traits
3. added support for dense matrix
4. removed unnecessary comparison when reading data line by line. (e.g.
   only read header line once)

e6e7efba8a COO: add push_matrix fn
- This function allows one to add entire dense matrices
to a sparse COO matrix.
- Added a small mention of this new function in the
example in lib.rs

7a083d50f7 Increase tolerance to ensure tests pass
It's possible that some particularly bad inputs cause
severe loss of significance in the triangular solves.
This is exacerbated by the fact that the way we test
the (residual) error is also prone to loss of significance,
so that the error measure itself is problematic.

We could maybe improve this in the future by using arbitrary-
precision arithmetic to remove some sources of error and testing
against appropriate bounds.

9cd1540496 Improve and test proptest generators
Due to a bug in proptest, we were required to pull in and modify
parts of proptest::strategy::Shuffle. Once the below PR has been merged
and released on crates.io, we can remove this code.

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.
