Update makeRefinedSimplexGeometry

* Add documentation
* Add support for operator() function interface
* Deprecate support for f.evaluate() function interface

The interface transition is done by borrowing
from dune-localfunctions. This allows to support both interfaces
for transition while giving a deprecation warning only if you
pass an old style function.
