// This will create the audio sample objects found throughout the NMC family of websites.
// The idea here is that a user clicks the Hear Audio button, the name of the audio sample
// is sent to the function, the function will check to see if another sample is all ready playing
// if a sample is all ready playing, it will check to see if it is the same sample that it was just passed
// If it is the same sample, we will do nothing, because the sample is currently playing and the user
// can control the flash player directly.
// If it is a different sample, we will first fade out the current audio sample, then remove it from the
// page entirely. After the initial sample is removed from the page, we will write the new embed code
// to the page using the audioSample variable as the source for the .mp3. These mp3s are stored in the
// audio folder (themes/NWR1/audio/stories). Their mp3 names must match the id of the toggle link.

// Available Variables and their default values
//	isPlaying = 0 This signals the program that an audio sample is playing, or not playing.
//  audioQueue = ""; This holds the value of the audio sample that should be played
//  audioCurrent =  "" ; This holds the value of what is currently being played

var audioCurrent;	// will hold current song playing

$(document).ready(function(){

	var isPlaying = 0;

	var audioQueue;		// will hold next song

		t = $(this); 				// set t to current element
		audioQueue = t.attr('id'); 	// grab the audio sample name from the id of the toggle link
