Broken but a start
Some progress
The new betamax tests should pass now
Environment variables in Travis are hard
Bump Betamax version
Ignore .env file
Cover create issue
Upgrade betamax dep
Found yet another bug in Betamax
Update cassette for a passing test
Bump betamax version again
Bump betamax once more
Update the default value for the placeholder

If I decide to start matching on headers this will be necessary
Start re-organizing the tests more intelligently
Remove empty file.
Clean up integration tests a bit
Remove duplicate tests
Allow removing milestone in Issue.edit()

Pass milestone=0 to remove a milestone.

This is new API from GitHub; they require passing a null milestone, so
change 0 to None after removing all the default None parameters from
the JSON dict.
Make all arguments of Milestone.update() optional

This makes it possible to do something like
milestone.update(state='closed') without resetting the title,
which seems closer to the purpose of the underlying GitHub
API.

In addition, previously, milestone.update(title=some_title,
state='closed') would error out because the optional
parameters were not removed before sending the request.
Test create key

- Record key deletion too
