merge gora-examples into gora-core test

[enis]

Having a separate gora-examples module is very logical and useful for the users. However, all of the tests for gora-core and the other modules depend on the data structures, and jobs at gora-examples. Until now, thanks to ivy, we have managed this as follows:
gora-core compile configuration does not depend on anything,
gora-examples compile dependency depends on gora-core
gora-core tests dependency depends on gora-examples.

What seems a cyclic dependency above was resolved by a clever build order among compile and test dependencies. However, this has proven to be a major source of headaches. So long story short, I propose we merge gora-examples into gora-core.
