Solved problem in RepresentationOverCoefficientsRing.

Now it will only return immutable matrices.

Tried to correct computation of reduced echelon form in IdealBasisToGroebner.

Is still not 100% correct.
Improved IdealBasisOverCoefficientsRing.

In case that all generators are zero over the residue class ring, the algorithm returns a zero matrix without any further computation.
skipped the reduction of Groebner basis in the function IdealBasisToGroebner.

There occured some problems I don't understand yet. Now the function returns a basis over the coefficients ring together with the groebner basis of the defining ideal of the residue class ring.

Computes the derivative of a univariate polynomial.
Added three examples.

Changed the most important example.

Exchanged the generators of the ideal by a Groebner Basis.
declared, installed and added example for FGLMToGroebner
Useless lines I don't want to see in the modified stuff of git anymore.
