 * @name MediaPlugin

 * @usage
 * ```typescript
 * import { MediaPlugin } from 'ionic-native';
 *
 *
 *
 * // Create a MediaPlugin instance.  Expects path to file or url as argument
 * // We can optionally pass a second argument to track the status of the media
 *
 * const onStatusUpdate = (status) => console.log(status);
 *
 * const file = new MediaPlugin('path/to/file.mp3', onStatusUpdate);
 *
 * // Catch the Success & Error Output
 * // Platform Quirks
 * // iOS calls success on completion of playback only
 * // Android calls success on completion of playback AND on release()
 * file.init.then(() => {
 *   console.log('Playback Finished');
 * }, (err) => {
 *   console.log('somthing went wrong! error code: ' + err.code + ' message: ' + err.message);
 * });
 *
 * // play the file
 * file.play();
 *
 * // pause the file
 * file.pause();
 *
 * // get current playback position
 * file.getCurrentPosition().then((position) => {
 *   console.log(position);
 * });
 *
 * // get file duration
 * file.getDuration();
 *
 * // skip to 10 seconds (expects int value in ms)
 * file.seekTo(10000);
 *
 * // stop playing the file
 * file.stop();
 *
 * // release the native audio resource
 * // Platform Quirks:
 * // iOS simply create a new instance and the old one will be overwritten
 * // Android you must call release() to destroy instances of media when you are done
 * file.release();
 *
 * // Recording to a file
 * var newFile = new MediaPlugin('path/to/file.mp3');
 * newFile.startRecord();
 *
 * newFile.stopRecord();
