Detailed Description
This class is the base class for all wavefunctions for use in helicity amplitude calculations. The general approach is to use a similar philosophy to the FORTRAN HELAS code but with additional structure.This class contains the storage of the particle type and 5-momentum and methods to set/access this information.
The methods for the wavefunction itself will be implemented in the classes derived from this one for the specific spin type, for example scalar, spinor, vector and tensor.
