Detailed Description

Author
Peter Richardson

This class is the base class for scalar 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 stores the scalar wavefunction as a complex number and inherits from the WaveFunctionBase class for the storage of the particles momentum and type.
