Context Navigation

Changes between Initial Version and Version 1 of Ticket #6534, comment 43

initial	v1
4	4	Meaning if you did `bp_core_remove_nav_item( $group_slug )` it would remove the group slug nav item and all group's subnav items.
5	5
6		In 2.6, we don't ~~use~~ yet the primary nav for the group, we just set one nav that is the group's slug this way even if it's a different object it still looks like before, all group nav items are in the secondary nav of the group's slug primary nav.
	6	In 2.6, we don't "fully" enjoy yet the primary nav for the group, we just set one nav that is the group's slug this way even if it's a different object it still looks like before, all group nav items are in the secondary nav of the group's slug primary nav.
7	7
8	8	So i guess the test for `bp_core_remove_nav_item( $group_slug )` is to check `$bp->groups->nav` is empty.
