[palkan]

Add a percentage of time spent in the event (from the total test suite/group/example time)

Before:

[TEST PROF INFO] EventProf results for factory.create

Total time: 03:07.353
Total events: 7459

Something (./my_spec.rb:21) – 09:16.100 (7 / 3)
...

After:

[TEST PROF INFO] EventProf results for factory.create

Total time: 03:07.353 of 07:25:232 (42.02%)
Total events: 7459

Something (./my_spec.rb:21) – 09:16.100 (7 / 3) of 12:29:233 (74.13%)

Hello there! May I take a look at this one?
Could you get into more details? I'm trying to understand what do you mean by total test time.

Hi!

May I take a look at this one?

Sure)

I'm trying to understand what do you mean by total test time.

That's the total time the test suite took (i.e. the sum of all examples total time spent).
