Known Subclasses:

Language independent base class for writing Helas calls. The calls are stored in two dictionaries, wavefunctions and amplitudes, with entries being a mapping from a set of spin, incoming/outgoing states and Lorentz structure to a function which writes the corresponding wavefunction/amplitude call (taking a HelasWavefunction/HelasAmplitude as argument).
