Get rid of toDate method and inherit from AbstractAdapter directly.
Add new method to handle toDate function.
Change back to pass connection as parameter.
Using getDBConnection rather than pass connection as a parameter.
made a ton of changes related to keeping oracle SQL code out of the main classes. fixed a bug where the timing of the index thread was off so when it went to index a document, the document was not already in xml_documents thus breaking the FK relation between xml_documents and xml_index. I think that bug might be the reason for the blank resultset screens in morpho. made the postgres implementation much more robust.
rename the DB* classes to:AbstractDatabaseOracleAdapterPostgresqlAdapterSqlserverAdapter
