		Template for adding a shortcode page to a plugin. Steps:
		
		1. Include this file.
		2. Add [my_page_shortcode] shortcode to a page of the site.
		3. Navigate to the page on the front end.
		
		Be sure to change the name of the shortcode and the function names below.
		
		Add all "preheader" code to the preheader section. This is code that will process before the wp_head call and should include form processing, etc.
		
		All frontend code should go in the page template section. We use output buffering to capture anything echo'd here and return it to the shortcode to be swapped into the shortcode space.
