	[Constructor]
	new Querystring([querystring]) 
	Creates a new Querystring object, optionally passing a string qs to parse. If qs is omitted, the querystring from the current page is used. 
	If querystring is passed, it should not begin with a "?". 
	// Parse the current page's querystring
	var qs = new Querystring()
	
	// Parse a given querystring
	var qs2 = new Querystring("name1=value1&name2=value2")
	
	[Methods]
	qs.get(name[, default_value]) 
	Returns the value of querystring parameter name if it exists, or default_value if it doesn't. 
	If default_value is omitted and parameter name doesn't exist, returns null. 
	var v1 = qs2.get("name1")
	var v3 = qs2.get("name3", "default value")
	
	Note: If a name appears more than once in a querystring only the last value is kept. 
	qs.contains(name) 
	Returns true if the querystring has a parameter name, else false. 
	if (qs2.contains("name1")){ alert(qs2.get("name1"));}
