A coverage reporter for Mocha/Blanket that will fail a travis-ci build when the coverage threshold is too low.

Threshold is specified in the package.json file of the consuming project.

Add the key `"travis-cov" to the "config" key in your package.json file. Under that key you can add any of the following properties:

threshold: <number>, global: <boolean>, local: <boolean>

See Blanket.js's package.json as an example.

###usage

1. npm install travis-cov
2. Use a reporter argument, mocha -R travis-cov
3. Change scripts.test in your package.json file to use mocha -R travis-cov
4. Add travis-cov to the package.json file in the config section. Add whichever keys you want (see above).
5. Set up your project with travis-ci
6. Commit, if your tests pass and the code coverage is above the threshold the build will pass, otherwise it will fail.
