Two condensed macro-elements with full approximation power

A variant of the classical C1 Powell-Sabin-12 macro-element is defined that has the same approximation power, but has fewer degrees of freedom and only requires vertex data. The same idea is then applied to a related C1 trivariate macro-element.
