kspoly.cc:
--> kscheckcoef
      * modified for zero divisors
--> ksCreateShortSPoly
      * create correct short s poly for rings
      * in case of rings, also calculate coeff

kstd2.cc:
--> bba
      * use different enterpairs method in case of rings
      * small changes (replaced p_ISet by p_NSet)

kutil.cc, kutil.h:
--> new enterpairs derivate, also downstreams are
     new derivates of functions
--> function to create extended s poly for rings
--> nComp fct, will be nGreater later, maybe
--> stub for chainCritRing

polys.cc:
--> chainCrit correct for rings, but not optimized

numbers.cc, rmodulo2m.cc, rmodulo2m.h:
--> gcd, ncd for zero divisor (att, not really a gcd or ncd)
--> IntDiv (att, just takes a machine div, allows to divide by zero div)
--> Greater (att, compares zero divisor exponent)
