import ampform_dpd.dynamics.builder

Dynamics builder functions for register_builder().

Note

As opposed to AmpForm, AmpForm-DPD defines dynamics over the entire decay chain, not a single isobar node. The dynamics classes and the corresponding builders would have to be extended to implement other dynamics lineshapes.
