1.  GeometryFactory() class needs to be re-designed so that it doesnt
require copying so many objects.  (Plus debugging)
2.  Coordinate and Coordinate list need looking at too.
CoordinateList.get() looks like its constructing new Coordinates each time
(at least from the profiler output).  Most of the time is spent in
constructing Coordiates and getting them.
3. quick CoordinateList constructor for an array of struct {double x,y,z}
points.  That is, if there is a better way than just converting each point
into a Coordinate and adding it to a CoordinateList.
