Detailed Description

Adds layers of cells to outside of polyPatch.

Call setRefinement with offset vector for every patch point and number of layers per patch face and number of layers per patch point.

offset vector should be zero for any non-manifold point and synchronised on coupled points before calling this.
offset vector of zero will not add any points.
gets supplied the number of extruded layers both per face and per point. Usually the point nlayers is the max of surrounding face nlayers.

point nlayers:

0 : no extrusion. Any surrounding face being extruded becomes 'prism'
>0 : should be max of surrounding face nlayers.

differing face nlayers: 'termination' : (e.g. from 2 to 4 layers) match at original patch face side.

E.g. 2 boundary faces on patches a,b. 2 layers for a, 3 for b.

Was:

   a  b <- patch of boundary face
+------+------+
|  |  | <- original cells
+------+------+

Becomes:

   a  b <- patch of boundary face
+------+------+
+  +------+
+------+------+
+------+------+
|  |  | <- original cells
+------+------+

added faces get same patchID as face they are extruded from
'side' faces (i.e. on the edge of pp) get the patchID of the other patch they are connected to.

E.g. 3 boundary faces on patches a,b. b gets extruded, a doesn't.

   a  b  b  <- patch of boundary face
+------+------+------+
|  |  |  |  <- cells
+------+------+------+


   ^  ^ <- wanted extrusion vector (none at far right)
   a   |  b   |  b  <- patch of boundary face
+------+------+------+
|  |  |  |  <- cells
+------+------+------+

  b
   +------+\ b  1. prism cell added onto second b face since
   a  a|  | ----\  only one side gets extruded.
+------+------+------+  2. side-face gets patch a, not b.

of indirectPrimitivePatch (have to be outside faces). Gets displacement per patch point.

nPointLayers : number of layers per (patch)point
nFaceLayers : number of layers per (patch) face
firstDisplacement : displacement per point for first layer of points (i.e. nearest to original mesh). If zero do not add point. Layer thicknesses are calculated to constant geometric expansion. Use expansionRatio 1 for constant size. Sets addedPoints_ which is per pp point a list of points added. Note: firstDisplacement has to be parallel synchronised before calling this routine. Only if all procs sharing a point get a cell should firstDisplacement be <> 0 Note: cells get added from owner cells of patch faces (instead of e.g. from patch faces)
