// A functor intended for use with the spatial subdivision set of classes.  It's 
// primary usage is to insert the first parameter into the second.  
// 
// Expected usage:
// When passed to the intersection objects intersection functions, this fucntor 
// inserts the first item into the second one.  Used primarily for inserting the
// different spatial sorted elements into their appropriate spatial subdivisions.
// For an example, see the gdbNode inserter class.

   // @returns Always returns false as it is never done processing - it can
