// Description:
//      Class AstAssociation
//      Very simple class to provide an association between two
//      pointer types which don't obviously belong together in a class,
//      but need to go together for some reason.
//
// Environment:
//      Software developed for the BaBar Detector at the SLAC B-Factory.
