Detailed Description
The sole purpose of a MeshBuffer is to hold storage space for the results of an HTM inetersection and then allow multiple MeshIterator's to walk through the result set.
The buffer space is allocated when the MeshBuffer is created. Mesh buffers will usually hang around for the life of an HTMesh. Each mesh buffer is re-usable. Simply reset() it and then fill it by append()'ing trixels. A MeshIterator grabs the size() and the buffer() so it can iterate over the results.
