Added a basic submodule level

[jackmaney]

Added a basic level for adding a (dummy) submodule. I got githug test to pass, but am not sure how to run the integration test (my Ruby-Fu is fairly weak...).

Huh... Looks like the Travis CI build failed for Ruby 1.8.7 (but passed for everything else). Unfortunately, the logs don't seem to indicate what's wrong:

..Cloning into 'githug-include-me'...
remote: Counting objects: 9, done.
remote: Compressing objects: 100% (6/6), done.
remote: Total 9 (delta 1), reused 0 (delta 0)
Unpacking objects: 100% (9/9), done.
Checking connectivity... done.

Is there any way to get a more detailed log of what's going on?

Just for the heck of it, I'm gonna close and reopen this to re-trigger a new build.

Ah ha! In Ruby 1.8.7, there is no exist? method in Dir. Hmmm.....

This is amazing. I followed the story all the way though. 10/10 - would merge again.

Thanks for the level, looks great.

You're more than welcome. :smiley:
