that would be cool, but unfortunately dolfin does not seem this functionality:
http://fenicsproject.org/documentation/dolfin/dev/python/programmers-reference/mesh/refinement/refine.html
the python interface takes as an input parameter a function that returns true
if a cell is to be refined and false otherwise.
in Octave I'd say we can use an arry of logicals or a function handle or allow
either of the two and check which one was passed.
