Tests: Code coverage

[Andy Nowacki]

It feels like there are not many tests for a package that contains so much functionality. If you cannot enable continuous code coverage checking via something like Codecov or Coveralls, I very strongly urge you to consider checking your code coverage locally (use julia --code-coverage) and trying to test more of the code.

You are right; code coverage at this point is low at 32%. Coveralls has been set up as of this commit. I will check back here once I’ve edited tests/runtests.jl.

As of this commit the test file covers all the code except the Plots recipes. I do not think testing the Plots recipes is particularly useful. Unfortunately, the coverage looks bad at 53%, but it’s an honest 53%.
