/**********************************************************************************
	NOTES:
	
	Our custom post type: Contract (uc_contract)

	Note that you must call register_post_type() 
	before the admin_menu and after the after_setup_theme action hooks. 
	A good hook to use is the 'init' hook. 
	
	Do pay close attention to not having your custom post type identifier 
	exceed 20 characters though, as the post_type column in the database 
	is currently a VARCHAR field of that length. 
	
	Read more about Custom Post types here: https://codex.wordpress.org/Post_Types
	
	QUESTIONS:
	
	1. do we need to register taxonomies ?  (param of capabilities)
