@jloveland good start. Can you also add Gulp support?

[jloveland]

@ilanbiala thanks for the review.

I would like to have the gulp karma coverage added in a different PR. Rationale is the following:

1. Mean.js doesn't fully support gulp yet
2. We don't even have a gulp coverage task for the server yet.

WDYT?

[jloveland]

also, what are your thoughts on outputting reports for client and server in coverage/client and coverage/server respectively?

👍 on adding coverage report for the client side
Sounds like a good idea to separate them for the future. People might be interested only in one aspect (client vs server) or will want to do different things with them in CI/CD process.

@lirantal and @ilanbiala fixed conflicts, this should be ready to merge.

[ilanbiala]

@lirantal should we see coverage in Coveralls already, or will we have to merge the PR?

[lirantal]

IIRC you must merge first because it's just tracking the master branch.
