/**
 * 
 * This tests basic operations on the modelRDB.
 * 
 * It adds/removes statements of different types and verifys
 * that the correct statements exist at the correct times.
 * 
 * To run, you must have a mySQL database operational on
 * localhost with a database name of "test" and allow use
 * by a user named "test" with an empty password.
 * 
 * (Based in part on earlier Jena tests by bwm, kers, et al.)
