Remove the file entitypointer.hh

Closes #49 and #57

See merge request !164

The file was still included, but it wasn't actually used.

Remove wrapper around `SurfaceElement`

See merge request !165

The `SurfaceElement` function is used nowhere and can be removed from
dune-uggrid once this wrapper is gone.

A small steps towards its complete removal.  Without the deprecated
methods it is easier to see the code that is still used.

Just to increase the pressure towards its complete removal.

Remove unused parameter 'res' from CreateBoundarySegment

Remove implementation of removed `count<codim>()` template method

See merge request !158

Ansgar Burchardt authored 8 years ago and Christoph Grüninger committed 8 years ago

The method was removed from the `Entity` facade class in

gridinfo.hh: Use `subEntities(codim)` method instead of removed `count<codim>()` template method

See merge request !157

The `count<codim>()` template method was removed from the `Entity` facade class in
0cfc8f31

Cleanup UGGrid code

See merge request !156

The implementation is identical for both level and leaf intersections.

The `WorldVector` and `FaceVector` typedefs are already used in some
method declarations and in the implementation.  This patch uses them
consistently everywhere.

The method signature of CreateBoundarySegment has change in dune-uggrid.
The 'res' parameter was not actually used anywhere.  Therefore it has
been removed.

[bugfix] avoid subscript operator on JacobianTransposed

See merge request !154

A geometry's JacobianTransposed implementation may be any type modelling a
linear mapping, i.e., implementing the mv-type methods. Some grids
(e.g., SPGrid) only implement this interface for performance reasons.
However, we require that a JacobianTransposed can be assigned to a
FieldMatrix.

This patch fixes "checkCodim1Mapping" such that it will cast the
JacobianTranposed down to a FieldMatrix before accessing the subscript
operator (although the same result could be achieved using "mv").
