Integrate lodash into the develop branch

I thought you might rather put the lodash integration into the develop branch (after reading the README a little more closely). I have configured the default grunt task to not run coverage, because right now the develop branch doesn't have enough coverage to pass the minimums that are in place.

I did add one spec file to increase the line coverage enough, but it also wants function coverage, which would require an additional 20 functions to be covered to meet the 25% minimum. That did sound as low-hanging a fruit as the additional 2% of line coverage did.
