	   document.getElementsBySelector(selector)
	   - returns an array of element objects from the current document
		 matching the CSS selector. Selectors can contain element names, 
		 class names and ids and can be nested. For example:
		 
		   elements = document.getElementsBySelect('div#main p a.external')
		 
		 Will return an array of all 'a' elements with 'external' in their 
		 class attribute that are contained inside 'p' elements that are 
		 contained inside the 'div' element which has id="main"
