Details - Currently the MCMGMapper gets the Layout class template as template parameter
and uses a static instance of this class to determine if a GeometryType should be
counted by the mapper. This is done using a nonstatic method of this instance

The attached patch changes the behaviour such that a nonstatic layout member is used. It also adds constructors to the mappers allowing to provide a custom layout object.

While this does not brake existing code (except for the ugly case it relies on the
use of single static member) it provides the possibility to use mappers for
different codims having the same type. Thus one could use an array containing
a mapper for each codim.

To be compatible with the current interface description the member is mutable. In the long term the contains method of layout classes should be const allowing the member to be const to.

One or more files have been attached.
