Golf Handicap Calculator

Works out the handicap for a user according to the UK CONGU regulations using a form generated with a shortcode ([ghc_form]). Will then update the handicap after the initial one is worked out every time the user enters a new card. This is then displayed in a table of all the members registered on the site (again with a shortcode ([ghc_display_users])). Admin can update the css from the settings panel and manually change a users handicap from their profile pages. You can also display the current users handicap with the shortcode [ghc_user_details].
