A Grid is a container of grid entities. An entity is parametrized by the codimension. An entity of codimension c in dimension d is a d-c dimensional object.
Entities of codimension 0 ("elements") are defined through template specialization. Note that this specialization has an extended interface compared to the general case
Entities of codimension 0 allow to visit all neighbors, where a neighbor is an entity of codimension 0 which has a common entity of codimension 1 with the These neighbors are accessed via an iterator. This allows the implementation of non-matching meshes. The number of neigbors may be different from the number of faces/edges of an element!

inline |
Location of this element relative to the father's reference element.
This information is sufficient to interpolate all dofs in conforming case. Nonconforming may require access to neighbors of father and computations with local coordinates. On the fly case is somewhat inefficient since dofs are visited several times. If we store interpolation matrices, this is tolerable.

Intra-level access to intersection with neighboring elements. A neighbor is an entity of codimension 0 which has an entity of codimension 1 in commen with this entity. Access to neighbors is provided using iterators. This allows meshes to be nonmatching. Returns iterator referencing the first neighbor.
