Removed unused libraries
Initial commit of SQL script
Added INVALID_VALUES tests
Removed the mandatory parameter KEY_FIELD_DELIMITER (was made redundant
by JSON implementation)
Fixed problem with SQLException not being thrown after an exception
occurred.
Improved exception handling flow (got rid of printStackTrace statements)
More clean-up on error-handling and removing unused libraries

manager.
Added handling for high water marks
Improved error handling
Changed temporary table random number generator multiplier to 1000000
(from 1000) to better ensure uniqueness in the table name.
Changed default batch size to 10000 for
SQLServerDatabasePersistenceProcessor to test for performance
improvement.
Removed redundant library references that were made invalid by
implementation of other classes
Execute all datasets [still a static list - needs to be automated fully]
