Detailed Description

Base class for cellshape matchers (hexMatch, prismMatch, etc.). These are classes which given a mesh and cell number find out the orientation of the cellShape and construct cell-vertex to mesh-vertex mapping and cell-face to mesh-face mapping.

For example,

    hexMatcher hex(mesh);
    cellShape shape;
    ..
    bool isHex = hex.match(celli, shape);

Now shape is set to the correct Hex cellShape (if isHex is true)

Alternatively there is direct access to the vertex and face mapping:

    const labelList& hexVertLabels = hex.vertLabels();
    const labelList& hexFaceLabels = hex.faceLabels();

Now

hexVertLabels[n] is vertex label of hex vertex n
hexFaceLabels[n] is face label of hex vertex n

Process of cellShape recognition consists of following steps:

renumber vertices of cell to local vertex numbers
construct (local to cell) addressing edge-to-faces
construct (local to cell) addressing vertex and face to index in face
find most unique face shape (e.g. triangle for prism)
walk (following either vertices in face or jumping from face to other face) to other faces and checking face sizes.
if necessary try other rotations of this face (only necessary for wedge, tet-wedge)
if necessary try other faces which most unique face shape (never necessary for hex degenerates)

The whole calculation is done such that no lists are allocated during cell checking. E.g. localFaces_ are always sized to hold max. number of possible face vertices and a separate list is filled which holds the actusl face sizes.

For now all hex-degenerates implemented. Numbering taken from picture in demoGuide.
