26 
27 Description
28  Base class of (analytical or triangulated) surface.
29  Encapsulates all the search routines. WIP.
30 
31  Information returned is usually a pointIndexHit:
32  - bool : was intersection/nearest found?
33  - point : intersection point or nearest point
34  - index : unique index on surface (e.g. triangle for triSurfaceMesh)
