Detailed Description

Takes mesh with 'baffles' (= boundary faces sharing points). Determines for selected points on boundary faces the 'point region' it is connected to. Each region can be visited by a cell-face-cell walk. Used in duplicating points after splitting baffles.

Regions are not consecutive per processor. They will be -1..nRegions_.

Note: coupled boundaries (cyclics, parallel) not fully tested.
