+Class
+    Foam::searchableSurface
+
+Description
+    Base class of (analytical or triangulated) surface.
+    Encapsulates all the search routines. WIP.
+
+    Information returned is usually a pointIndexHit:
+    - bool  : was intersection/nearest found?
+    - point : intersection point or nearest point
+    - index : unique index on surface (e.g. triangle for triSurfaceMesh)
