+//  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.
