// This variation of the script introduces a queue system for the mySimpleAds loader
// which is useful if you have more than one ad zone div on the page and you are
// loading banners into them remotely using the mysa_loadad function
// -------------------------------------------------
// Usage: Instead of calling the mysa_loadad(mysa_url,mysa_id) function, call
// the mysa_queue_loadad function(mysa_url,mysa_id,mysa_append).
// Then, call the mysa_queue_execute() function in your body onLoad.
// -------------------------------------------------
// If you pass the mysa_append variable as "append", instead of
// overwriting what's in the div, it will append the new data.
// -------------------------------------------------
// Script will also turn the display of a div to block if it was previously none.
