Working on moving to the new Polynomial classes for the stable algorithm
Swapped the in progress file and the original
Starting on the unit tests for the stable alg
Added a polynomial shift algorithm and a eval_derivative to allow testing of the stable event finding routines.
Adding stable algorithm tests
Isolated an error in the stable formula
More work on unit tests for the stable algorithm
More work
Implemented euclidean division for polynomials and cleaned up the polynomial shift algorithm
Implemented Sturm chains for the Polynomial class
