//
//  This is the abstract base class of the user's mandatory action class
// for primary vertex/particle generation. This class has only one pure
// virtual method GeneratePrimaries() which is invoked from G4RunManager
// during the event loop.
//  Note that this class is NOT intended for generating primary vertex/particle
// by itself. This class should 
//  - have one or more G4VPrimaryGenerator concrete classes such as G4ParticleGun 
//  - set/change properties of generator(s)
//  - pass G4Event object so that the generator(s) can generate primaries.
