adds row and column iterators for sparse matrices

4

A nice convenience iterator that I end up using often. Iterates over `(column_index, &T)` for CSR rows and `(row_index, &T)` for CSC columns (and mutable counterparts).

Parallel Matrix Operations

Currently only sparse by sparse products are parallel in the `smmp` module. Converting the current sparse by dense products using `ndarray::parallel` should be straight forward. Here is an implementation for...

sparse by dense parallel products #298

2

Starts on #298. Using `ndarray` parallel iterators this is the naive conversion of the sparse by dense products to a multithreaded implementation. Ideally, there is a `rayon` `into_par_iter` implemenation for...
