Add a skeleton for the front-end

[Pranay92]

Use the following:

1. AngularJS because it's awesome
2. Use angular-ui,angular-bootstrap because they make integration with the angular easier
3. Lodash because we'll be dealing with the collections a lot time

Avoid using libraries that aren't doing too much because they might end up increasing the size of your application and thus slow loading. Prefer creating own module/directive for features that can be created easily rather than using others.
