Upgrade from Underscore.js to Lodash.js #62
Description
Lodash: https://github.com/lodash/lodash
Lodash (originally a fork of Underscore) has a build which is a drop-in replacement for Underscore.js, with better testing, better performance, etc.
If you're willing to do some work to upgrade, you can also use the new API which includes more functionality than Underscore.
