This introduces: * asyncronous event generation * possibility for parallel event generation This is useful for: * hiding latency (IO) of certain generators * decoupling the actual work from the call sequence into HybridGenerator * collaboration from multiple clones of the same generator to generate a certain number of events The implementation relies on tbb::task_arena and input/output queues for decoupling the task_arena from the HybridGenerator thread. An example is added for parallel event gen. In addition, this commit has the following changes: - Small adjustments to seeding of Pythia8 in order to avoid same seeds in multiple parallel Pythia instances. - possibility to init external generator from an INI file (typically done or available in O2DPG) - use shared_ptr instead of unique_ptr to keep generators in order to avoid lifetime problems with async processing - preparion to run underlying generator Init() functions in async way (not active yet; needs checks if generators are thread safe)
