Also added MakeableInterfaceObject class which can create InterfaceObjects
like Entity. this is used to get rid of the MakeableEnttiy,
MakeableGeometry everywhere, but oone also can use the MakeableEntity
strategy as before. This finishes Task #63.

have the full set of methods as the higher-dimensional geometries.

It would be possible to provide default implementations for the new
dim=0 methods in the wrapper class.  This would not lead to any
efficiency problems, as any if(mydim==0) can get optimized away.
However, the different grid implementations still need to have
the functions in order to have the code compile.  So for now I
didn't include default implementations.

only UGGrid supports grids with more than one element type.

[[Imported from SVN: r4059]]

the index disregards the GeometryType.  That is, indices are consecutive
and zero-starting in one set.  This is usefull for element or face data
on grids with more than one element type.

You can instantiate a PanTypeIndexSet by given it a Level- or LeafIndexSet.
