A simple type to manage the membership of a group, from the perspective of the group.

It is worth noting, if you are using this model of membership, you should not be using the groups parameter on the user type.

groupmembership { 'trees':
  members => ['oak','elm']
}

Pretty easy, right?

There is also an exclusive option to ensure that the only members of a group are those that have been expressed as part of the members parameter.

On OSX, you will need the plist gem.
