+IMPROVED: more efficient trimming

+The trim routine (which is used for the Finite Cell Method) is rewritten for

+introduce auxiliary vertices at every dimension (lines, faces, volumes), the
+new implementation limits the introduction of vertices to the line segments
+only, resulting in a subdivision that consists of fewer simplices and
+consequently fewer quadrature points.
