At the moment it is possible to attach an object to a selection (mempoint) of another object, with offset relative to that selection, but it's not possible to then get which mempoint the object is attached to. attachedTo only returns the overall object.
It would be useful if attachedTo could do that.

Proposed syntax:

attachedTo [_object]; // returns array in format [_parentObject, "selectionName", _isFollowingBoneRotation]
attachedObjects [_object]; // returns array of arrays in format [[_childobject1, "selectionName", _isFollowingBoneRotation], [_childobject2, "selectionName2", _isFollowingBoneRotation]]
