Detailed Description

IOoject and searching on distributed triSurface. All processor hold (possibly overlapping) part of the overall surface. All queries are distributed to the processor that can answer it and the result sent back.

Can work in three modes:

follow : makes sure each processor has all the triangles inside the externally provided bounding box (usually the mesh bounding box). Guarantees minimum amount of communication since mesh-local queries should be answerable without any comms.
independent : surface is decomposed according to the triangle centres so the decomposition might be radically different from the mesh decomposition. Guarantees best memory balance but at the expense of more communication.
frozen : no change

bounding boxes. Will do redistribution of surface to locally have all triangles overlapping bounds. Larger bounds: more triangles (memory), more fully local tests (quick). keepNonLocal = true : keep triangles that do not overlap any processor bounds. Should really be split into a routine to determine decomposition and one that does actual distribution but determining decomposition with duplicate triangle merging requires same amount as work as actual distribution.
