jQuery.fn.unwrap = function () {
	///	<summary>
	///		Removes the immediate parent wrapping element from each element of the matched set.
	/// 	For elements in the matched set that share a common parent, the common parent element
	/// 	is removed.
	///	</summary>
	///	<returns type="jQuery">
	///		Returns the original jQuery matched set.
	/// </returns>
	/// <remarks>
	/// 	To keep things simple, I have avoided adding a selector argument to this extension.
	/// 	I suppose I could add it, but perhaps that is best done with a .filter() before
	/// 	calling .unwrap(). If you have an opinion about this, let me know.
	/// 	
	/// 	New for version 1.1, elements in the wrapped set that are direct children of the
	/// 	body tag will not be unwrapped, because doing so would delete the body tag.
	/// </remarks>
