/**
 * This exception is thrown if there is an error in the reasoning engine -
 * this should only happen if the engine is given invalid input. Parsers should
 * be written to prevent the creation of data structures that will not be valid
 * input for the reasoning engine.
 *
 * If a EngineException is thrown then it is likely that there is a bug with
 * the parser that is causing it to generate invalid data structures. It is
 * also possible that the user continues to use clause/term data structures that
 * were created before a call to the reset() method of jdrew.oo.util.Types or
 * jdrew.oo.util.SymbolTable.
