Organic groups affiliations

Provides the ability to 'affiliate' (link, relate, etc.) organic groups to one another using a workflow similar to how users join groups. Includes settings to specify which types can be affiliated to one another, and uses Views to produce lists of affiliations by type and status.

Module is stable but needs further enhancements such as integration with notifications, etc. Currently, pending affiliation requests are presented to group admins through Views-based page linked from menu tab.

Initial development of module was sponsored by ProInvest and performed by Optaros.
