OG Member Cascade

Manage OG membership inheritance in hierarchical group structures.Works for tree group hierarchies as well.

Note that group memberships (i.e. membership inheritance) are reset as per their user-defined settings upon updates of the group type. For example, suppose you have set Supergroup A to cascade members into Group B, and you later remove a couple of those members from Group B, but not from Supergrou A. At this point, editing Supergroup A's settings will cascade the two removed members from Supergroup A back into Group B.

Instructions:
- On install, the module creates the fields OG Member Cascade -- Member Cascade(boolean) and OG Member Cascade -- Supergroup Ref(entity reference). Add these fields to your OG hierarchical groups.

- About the fields: Member Cascade allows you to choose whether to cascade this group's memberships into its subgroup(s). Supergroup Ref allows you to specify this group's supergroups. Both of these fields must be set in appropriate relation to the group hierarchy for membership cascading to occur.

Example: To cascade members from Supergroup A into Group B, Supergroup A needs to set Member Cascade to "Yes", and Group B needs to select Supergroup A in Supergroup Ref.
