/* This file is concerned with anything in the Manage Membergroups screen.

	void ModifyMembergroups()
		- entrance point of the 'Manage Membergroups' center.
		- called by ?action=admin;area=membergroups.
		- loads the ManageMembergroups template.
		- loads the MangeMembers language file.
		- requires the manage_membergroups or the admin_forum permission.
		- calls a function based on the given subaction.
		- defaults to sub action 'index' or without manage_membergroup
		  permissions to 'settings'.

	void MembergroupIndex()
		- shows an overview of the current membergroups.
		- called by ?action=admin;area=membergroups.
		- requires the manage_membergroups permission.
		- uses the main ManageMembergroups template.
		- splits the membergroups in regular ones and post count based groups.
		- also counts the number of members part of each membergroup.

	void AddMembergroup()
		- allows to add a membergroup and set some initial properties.
		- called by ?action=admin;area=membergroups;sa=add.
		- requires the manage_membergroups permission.
		- uses the new_group sub template of ManageMembergroups.
		- allows to use a predefined permission profile or copy one from
		  another group.
		- redirects to action=admin;area=membergroups;sa=edit;group=x.

	void DeleteMembergroup()
		- deletes a membergroup by URL.
		- called by ?action=admin;area=membergroups;sa=delete;group=x;session_var=y.
		- requires the manage_membergroups permission.
		- redirects to ?action=admin;area=membergroups.

	void EditMembergroup()
		- screen to edit a specific membergroup.
		- called by ?action=admin;area=membergroups;sa=edit;group=x.
		- requires the manage_membergroups permission.
		- uses the edit_group sub template of ManageMembergroups.
		- also handles the delete button of the edit form.
		- redirects to ?action=admin;area=membergroups.

	void ModifyMembergroupsettings()
		- set some general membergroup settings and permissions.
		- called by ?action=admin;area=membergroups;sa=settings
		- requires the admin_forum permission (and manage_permissions for
		  changing permissions)
		- uses membergroup_settings sub template of ManageMembergroups.
		- redirects to itself.
