Detailed Description

StandardModelBase is used to handle standard model parameters in an EventGenerator.

It uses AlphaEMBase, AlphaSBase and CKMBase to help with the implementation of the electro-magnetic and QCD couplings and the flavour mixing matrix. This means that StandardModelBase does not need to be inherited from when it comes to standard model parameters. Beyond the standard model parameters should be implemented as sub-classes.
