30 // Description: Singleton class to evaluate two-body angular distribution
31 // functions based on intial/final state codes.
32 //
33 // 20130307 M. Kelsey -- Add verbosity interface for contained objects
34 // 20130422 M. Kelsey -- Add three-body distributions, for temporary use
35 // 20130619 Change singleton instance to be thread-local, to avoid collisions.
36 // 20130620 Address Coverity warnings about missing copy actions
