Backbone.Model File Upload
==========================
A concise, non-iframe, & pure XHR2/AJAX Backbone.model file upload.
A concise, non-iframe, & pure XHR2/AJAX Backbone.model file upload. (Good for IE >= 9, FF, Chrome.)
This plugin upgrades the current `save` method to be able to upload files.
This plugin upgrades the current `save` method to be able to upload files using the HTML5's File API and FormData class.
NOTE: This plugin will require deep parsing in the back-end since it won't be using a JSON object. In other words, your normal JSON serialization won't work here. It will convert the model to a key/value pattern. Model will be flattened on request.

In terms of how to use these methods, they have not changed. The only difference is that it has the capability to take a File object grabbed from the DOM (i.e. `<input type="file" />`). As the file is being uploaded, a trigger `progress` is being sent as the browser sends chunks of data. The `progress` trigger sends a progress status in percents.
