 should move to a utility class, as we now have more than  one class
 using this (which is why it changed to public static)

<DL>
<DD>Handles Geometry Filter encoding. Currently only supports the encoding
 of GEOMETRY_BBOX filters. If a GEOMETRY_BBOX filter is encounter it
 will be converted into an SDO_RELATE() function. If another filter is
 found, nothing will happen.

 does nothing, and should not be called, not included in the
