// Class that defines primary generator action. 
// Available primary generators (AliPrimaryGenerator):
//  kGun,               // gun (can be set interactively) 
//  kGeantino,          // geantino with random direction
//  kChargedGeantino,   // chargedgeantino with random direction
//  kAliGenerator       // AliGenerator from AliRoot
