-//     Function: get_transition_into
-//  Description: This external template function is handy for
-//               extracting a transition of a particular type from the
-//               set.  If the transition exists, it is automatically
-//               downcasted to the correct type and stored in the
-//               pointer given in the first parameter, and the return
-//               value is true.  If the transition does not exist, the
-//               pointer is filled with NULL and the return value is
-//               false.
