Title: Put contextLimitedPolynomal and contextInequalities back into one file

This replaces the `contextLimitedPolynomial.pl` and `contextInequalities.pl` files y their unified originals (removing the separate modules in `pg/lib`). It completes the update to handle the package errors that were happening during perl garbage collection when certain MathObjects were freed in the dispatcher.
