// PrologException
/**
* PrologException instances wrap Prolog exceptions thrown (either by a Prolog engine or by user code)
* in the course of finding a solution to a Query. See JPLException for the handling of errors within the JPL Java-calls-Prolog interface.
* <p>
* This class allows Java code which uses JPL's Java-calls-Prolog API to handle
* Prolog exceptions, which is in general necessary for hybrid Java+Prolog programming.
* <p>
* Use the term() accessor to obtain a Term representation of the term that was
* thrown from within Prolog.
