Iterate over all events providing all information available

[maxnoe]

Adressing #212 , I think it would just be better to provide an iterator that yields all events, providing what information is available.

So a non triggered event would only contain mc_shower and mc_event (and possibly the photons) while a triggered event would additionally contain the telescope data / array trigger information.

Like this, the simulated events info could be generated in the same event loop as the normal analysis.

I like it.

Yes this would be perfect
