Does nothing in Olivers classes yet.

This is needed to assemble the transfer operator (remember the SKIP
flags in UG?)

There are two versions of each of the methods addCellData/addVertexData
1) From a vector container of appropriate size
2) From a VTKFunction object that allows local evaluation
   => The P0Function and P1Function define adapters to VTKFunctions
   In Fact, any GridFunction can be wrapped up as an argument

For the coarse solver the right hand side has to be consitent
everywhere. Fixed the code to do this.

index of the first vertex is not in the set other vertices of the same
aggregate might be represented there. Therefore we now check all of
them whether they present anf if one is present the coarse index set
will get an according index for the aggregate.

This function is needed in AMG to prepare the right hand side for the
coarse solver.
