AngularJS file input handling directive

input-type-file.js

(function () {
'use strict';

angular.module('app.Components.InputTypeFile', [])

// When required, this module will automatically handle
// `ng-model` in file inputs.
//
// Usage:
//
//    <input type="file" ng-model="myModel" accept="image/*" multiple maxsize="100000">
//
// Options:
// - `multiple` (optional) if specified, the ng-model will be an array of the selected files
//   otherwise it will be a single file;
// - `accept` (optional) if specified, an angular `accept` validator will be added to check 
//   for files' mime type
// - `maxsize` (optional) if specified, an angular `maxsize` validator will be added to check
//   for files' size
