Description
Currently we have a C0- and a C1LocalBasis base interface and corresponding C0- and C1LocalBasisTraits. This complicates the interface for no reason, thus I suggest to remove this differentiation:
Either C0/C1 means piecewise C0/C1. Then there will hardly be relevant shapefunctions that are piecewise C0 and not C1. In the esoteric case of everywhere continuous and nowhere differentiable functions we could throw an exception.
If the regularity is not meant in a piecewise sense then this differentiation is much to coarse. E.g. the RefinedP1LocalBasis is piecewise but not globally C1. Since one needs the gradients the C0 interface is not sufficient. Furthermore RefinedP0 is not even continuous but one needs the function values.
