Fixing logParser error thrown for too short jobs with 10k events \#88

Description of bug

When logParser is run on very short jobs where 10k events can be produced in under 1h it throws an error.

- CPU =   0.33 hrs <-- ERROR: Too low CPU time - should be between 6-12h. Adjust nEventsPerJob! 

This is because we are using

elif cpuPerJob < 1.:
  if CountHepMC < 10000

i.e. the number of events in log.generate instead of the number of events in the jO.

See #88 (closed)

Changes introduced

Change above statement to cover both cases, i.e. both when jO is run with a limited number of events and when it is run without any restriction.

Tests

I 've run logParser for the log.generate file that @spalazzo provided and the error is gone.

Issues resolved

Closes #88 (closed)
