Method 'contains' of MultipleCodimMultipleGeomTypeMapper is broken

Hi,

in dune/grid/common/mcmgmapper.hh, the MultipleCodimMultipleGeomTypeMapper class defines a templated method contains that should return true if the entity given in parameter is contained in the index set. However, the line 195 result = map(e); that should return the index of the entity doesn't make sense and raises an error. It should be replaced by result = is.index(e);

I attached a short example of code gettingstarted.cc that tries to call that method and the error log raised error.log
