Description

What exactly is the semantics of the insertBoundarySegment method without a boundary segment? Obviously, this gives me an insertion index for the boundary segment. But what does it mean for the boundary during refinement? I have 2 interpretations: (a) the boundary segment is linear (n-linear). (b) the boundary segment the trace of the adjacent element's geometry. I admit that the two definitions coincide on all implemented grids. Nevertheless, the answer might have an impact on which of the methods grid readers should use (especially once we support insertElement( type, vertices, elementParametrization ).

By the way: The documentation states: "Method to insert an arbitrarily shaped boundary segment into a coarse grid". This seems to be wrong.
