There were written for a Refractions customer; Oracle was threatening to 
take the JGeometry classes away - and the customer wanted an escape 
option. Oracle seems to have changed its mind. The JTS project also has 
a port of these SDO classes; it is kind of nice to go straight from 
SDO_GEOMETRY (ie the STRUCT) to JTS and Back. When I wrote the class I 
went for correctness over speed.
