Pool::size and Pool::alignedSize have to be at least the size of a
pointer as the free element are managed through a single linked list.

WARNING:  This will not work for vector-valued DiscFuncArrays.  I
didn't know how to do that correctly.

This is done temporarily because I want to remove MGTransfer which does
the same thing as MultiGridTransfer but uses the deprecated SparseRowMatrix.

After talking with Rbert I moved the access to the indices into a seperate
class (here YaspIndex). Thus we can change and add indices more easily
in the future (although I would not overuse this fact). Moreover, the
grid can build up the indices "on demand" only if they are requested.

If you want to see a mapper then look into dune-dd/mapper.hh

However, the Index class is still missing

These triangle, hexahedron, ... should be replaced from now on
because this simplifies the writing of dimension independent code.
The old types are still supported in appropriate places though.

added three new size methods. I implemented dummy versions (throwing
exceptions) in onedgrid, uggrid.
Working versions are implemented in yaspgrid and sgrid

throw exception for LeafIterator depending on PartitionIteratorType which
is not standard
