Detailed Description

template<class GridImp>
class Dune::ALU2dGridIntersectionBase< GridImp >

Mesh entities of codimension 0 ("elements") allow to visit all neighbors, wh a neighbor is an entity of codimension 0 which has a common entity of codimens These neighbors are accessed via a IntersectionIterator. This allows the implement non-matching meshes. The number of neigbors may be different from the number o of an element!
