// From Bill Tannenbaum:
// You can use
//   pset.getParameterAsString(aString).
// This function was added with the new tag.
//   However, there is a possible complication if the parameter in question is
//   itself a ParameterSet or a vector of ParameterSets.  In the new format, a
//   ParameterSet cannot be converted to a string until its ID is calculated,
//   which happens when it is registered.  So, if you get error messages about
//   not being able to convert an unregistered ParameterSet to a string, you can
//   do one of two things:
// A) You can use ParameterSet::dump() to print the parameter set, instead of
//    getParameterAsString().  This does not require registering.  I'm not sure of
//    the exact format of the dump output (Rick wrote this, I think).
// OR
// B) You can use ParameterSet::registerIt() to register the parameter set
//    before calling getParameterAsString().
//
// In either case, you can use existsAs to determine which parameters are
// themselves parameter sets or vectors of parameter sets.
//
// Note that in the new parameter set format, ParameterSet::toString() does not
// write out nested parameter sets by value.  It writes them out by
// "reference", i.e it writes the ID.
