CLASS METHODS:

	fetch($URI)
	-----------
	
	This is the method used for fetching the contents of a web page.
	$URI is the fully qualified URL of the page to fetch.
	The results of the fetch are stored in $this->results.
	If you are fetching frames, then $this->results
	contains each frame fetched in an array.
		
	fetchtext($URI)
	---------------	
	
	This behaves exactly like fetch() except that it only returns
	the text from the page, stripping out html tags and other
	irrelevant data.		

	fetchform($URI)
	---------------	
	
	This behaves exactly like fetch() except that it only returns
	the form elements from the page, stripping out html tags and other
	irrelevant data.		

	fetchlinks($URI)
	----------------

	This behaves exactly like fetch() except that it only returns
	the links from the page. By default, relative links are
	converted to their fully qualified URL form.

	This submits a form to the specified $URI. $formvars is an
	array of the form variables to pass.
