Limit number of events used to assess level #11

With large numbers of historical events the application starts to lag when assessing the users level. This provides a fix that keeps "good-enough" functionality.

Profiling found that most of the time is in creating new event objects when we unfold them per key.

Mostly addresses #10

Thank you, this looks very promising!
