   =========================================================================
   Photon map types and interface to nearest neighbour lookups in underlying
   point cloud data structure.
   
   The default data structure is an in-core kd-tree (see pmapkdt.{h,c}).
   This can be overriden with the PMAP_OOC compiletime switch, which enables
   an out-of-core octree (see oococt.{h,c}).
