father and ownersFather method modified slightly.
fixed bug in mapVertices method.
implemented entity method new.
modfied setElInfo methode due to removal of elNum.
modified implementation of local using th multAssign method.

AlbertaGrid passes gridcheck of dune.

Removed some useless code.

[[Imported from SVN: r1633]]

removed elNum from Entity class.

Removed some useless methods, like getTime and markNew on class Grid.
i.e. clean up.

Also implemented edge numbering for 3d, but not tested right now.

Furthermore improved the maxlevel calc and manIndex calc.

Now the level index is calculated using the DefaultLevelIndexSet
implemented in defaultindexsets.hh

Furthermore a const version of the getRealEntity method added.

be inherited from the GridDefault class.

This means that now instead of the class name the implemented has to
provide the full class type, such as SGrid <dim,dimworld> instead of only
SGrid.

Furthermore added leafbegin and leafend with PartitionIteratorType
template.
