description:
Reimplemented some existing algorithms in the SSA class,
cleaner code and more lightweigth operations with integers
should result in faster operation.

description:
Added class SSA to represent a sequence of expressions in static single assignment form,
with functionality to compute dependencies and derivatives. This is to be used for
improvement of the Jacobi computation, hopefully leading to a performance increase
without much more work.
