70  * This class provides escape handling mechanism for SapDB. Sap is a little
71  * different from many other databases, probably because a lot of it is Pascal
72  * based. Either way, it handles backslashes just fine, but it will choke on
73  * single quotes unless they are made ''. Double quotes for now are still
74  * gobbled up.
