Comment(by jason):
This already works. The problem is that it is backwardly-named
solve_left. The solve_right function incurs the overhead of a matrix copy
(but then solves the backwards equation, since solve_left is backwards).
To fix all this:
1. Rename the matrix_double_dense.pyx solve_left to solve_right
2. implement a matrix_double_dense.pyx solve_left that takes the
transpose and then calls solve_right
Eventually, we also need to fix the lu solve. There is another trac
ticket for this somewhere. The problem is that the function does not deal
correctly with the output of the scipy lu decomposition.
