Rewrite of Stellar.js native AngularJS directives without jQuery dependency

LiveScript is a compile-to-js language, which provides us more robust way to write JavaScript.
It also has great readibility and lots of syntax sugar just like you're writting python/ruby.

Stellar.js provides the same interface with angular directives.
We use the similarity between them and provides seamless intergration with Stellar.js.

This project follows DRY principle and has two dependencies, which are angularjs and ui.bootstrap.position.

• Download and include position.js.
• Download and include angular-stellar.js OR angular-stellar.min.js.

Then include them through script tag in your HTML.

Add this line to your application's Gemfile:

gem 'angular-stellar'

And then execute:

$ bundle

If you are NOT using angular-ui/bootstrap, you have to download position.js and put it in vendor/assets/javascripts/

Then add these lines to the top of your app/assets/javascripts/application.js file:

//= require angular
//= require ui-bootstrap-tpls
(`//= require position` instead if you aren't using boostrap)
//= require angular-stellar

And include in your angular module definition:

/* 'angular.stellar' DO depend on 'ui.bootstrap.position' module.
 */    
var module = angular.module('my-awesome-project', [/* 'bootstrap', */ 'angular.stellar']).

default to: 'scroll'

Available options are 'position', 'margin', 'transform', or you can define it yourself.

default to: 'position'

Available options are 'transform', or you can define it yourself.

default to: true

Whether or not to enable scrolling in horizontal, only apply to stellar-ratio elements.

default to: true

Whether or not to enable scrolling in vertical, only apply to stellar-ratio elements.

default to: 0

Global offset added to each element.

default to: 0

Global offset added to each element.

default to: true

When stellar-ratio elements are scrolled outside of visible area, hide them.

default to: function(it){ it.addClass('ng-hide'); }

You can have your implementation on your own.

default to: function(it){ it.removeClass('ng-hide'); }

You can have your implementation on your own.

default to: function(it){ return it.hasClass('ng-hide'); }

You can have your implementation on your own.
