 set pt spectrum for species, override default

 set pt dependent v2 for species, override default

 generate a flow event according to settings provided in GENERATOR INTERFACE

 convert the content of a tclones array to an aliflowevent simple for output and tag particles as poi's and rp's
 first step, see if there's already a flow event available in memory. if not create one

 afterburner, adds v2, uses Newton-Raphson iteration

 afterburner, adds v2 for different species to all tracks in an event

 generate tracks for the event. the tracks that are generated here are the mothers

 decay the tracks using a decayer that is set in the GenerateEventsOnTheFly.C macro

 force gama decay

 initializes generators for a list of common particles
 new generators will be created 'on the fly' if they are encountered
 if a generator is requested for a non-existent pdg value, things will get unstable ...

 make sure all went ok

 this function loops over all the species that are available in the fGenerators, which are
 a) created by the user (in the event generator) as mother particles or
 b) introduced by pythia (the decayer) as daughter particles
 c) made by the InitGenerators() function
 'empty species' (i.e. species for which a generator exists but which were not actually sampled) are omitted
 the output histograms are written to a file named "GeneratorfQA.root"

 general
