* Conditional tag to check if a user can view a specific post, by checking if they can see the forum that it belongs to.
* Non-logged in site visitors cannot view posts if groups were selected for the forum they belong to.
* A user cannot view a post if their group role has not been selected in the meta box on the edit forum screen in the dashboard.
* If no groups were selected, all users and site visitors can view the content.
* Keymasters can always view, and moderators with no group set can view
*

*Some of this code is Justin Tadlocks' from the members plugin - thanks Justin for awesome work !
