Class
    Foam::surfaceLocation
 
Description
    Contains information about location on a triSurface:
    - pointIndexHit:
        - location
        - bool: hit/miss
        - index (of triangle/point/edge)
    - elementType():
        - what index above relates to. In triangle::proxType
    - triangle():
        - last known triangle
