jjg@946:  *  Wrap objects to enable unchecked exceptions to be caught and handled.
jjg@946:  *
jjg@946:  *  For each method, exceptions are handled as follows:
jjg@946:  *  <ul>
jjg@946:  *  <li>Checked exceptions are left alone and propogate upwards in the
jjg@946:  *      obvious way, since they are an expected aspect of the method's
jjg@946:  *      specification.
jjg@946:  *  <li>Unchecked exceptions which have already been caught and wrapped in
jjg@946:  *      ClientCodeException are left alone to continue propogating upwards.
jjg@946:  *  <li>All other unchecked exceptions (i.e. subtypes of RuntimeException
jjg@946:  *      and Error) and caught, and rethrown as a ClientCodeException with
jjg@946:  *      its cause set to the original exception.
jjg@946:  *  </ul>
jjg@946:  *
jjg@946:  *  The intent is that ClientCodeException can be caught at an appropriate point
jjg@946:  *  in the program and can be distinguished from any unanticipated unchecked
jjg@946:  *  exceptions arising in the main body of the code (i.e. bugs.) When the
jjg@946:  *  ClientCodeException has been caught, either a suitable message can be
jjg@946:  *  generated, or if appropriate, the original cause can be rethrown.
