 	Designed to take a P&T list item and turn it into an anchor element.

	Splits the input around a delimiter of | (pipe)
	
	So, in the list enter "the text of a link | the location of the link", like so
		
		My Link|http://example.com
		
		or 
		
		My Link | /directory/template
		
		(spaces around the delimiter are optional to enhance legibility in the CP)
		
	Plugin returns
	
	 <a href="http://example.com" title="My Link">My Link</a>
	
	or
	
	<a href="/directory/template" title="My Link">My Link</a>
	
	In you template code 
	
	{p&t_list_field_name}
	{exp:list_linker item="{item}"}
	{/p&t_list_field_name}
	
<?php
		$buffer = ob_get_contents();
		ob_end_clean();
		return $buffer;
	}
}
