Augments the IMEX sweeper with a range of functions to generate the matrices representing one or multiple sweeps in matrix form. Having those functions all in one place allows to automate their testing.
Modifies test_imexsweeper to verify that matrix sweeps and normal sweeps are equivalent.
Fixes #57
