AudioBuffer loader and other loader utilities module

Load loaders.js in your html file by using:

    <script src="loaders.js"></script>

  // We need an audio context to decode the file
  // By default,the loaders search for audioContext in the window.
  var audioContext = new AudioContext();

  // Load the file passing the path
  var myAudioBufferLoader = new loaders.AudioBufferLoader();
  myAudioBufferLoader.progressCallback = function(obj){
    // Do something with the progress value obj
    // obj: {value:.., total:..., loaded:...}
    // value is loaded/total
  }
  myAudioBufferLoader.load('sound/file/url').then(
      function(buffer){
        // Do something with the loaded audio buffer
      },
      function(error){
        // Catch an error during the loading or decodeAudioData process
      }
  );

Use the same load method to load multiple files, by passing an array of urls ['url/to/file1', 'url/to/file2', ...]. The progress is then an object, eg. {index: 4, value: 0.2, total:999, loaded:1}, where index corresponds to the file index in the array of files, and value, between 0.0 and 1, corresponds to the file loading progress.
