We need a method for building a Jordan form for matrices

[SamoylovMD]

If we find fast algorithm (for O(n^3) time) for transforming matrix to Jordan form, we can use this to fast rank calculation, eigenvalues and eigenvectors finding, and other useful things.

This might be a good idea for the next milestone (0.5.0).
