This is the controller for ij. It uses two parsers: one to grab the next statement, and another to see if it is an ij command, and if so execute it. If it is not an ij command, it is treated as a JSQL statement and executed against the current connection. ijParser controls the current connection, and so contains all of the state information for executing JSQL statements.

This was written to facilitate a test harness for language functionality tests.
