group_removed

Description:

public signal void group_removed (Group group, GenericArray<Container> children)

Will be emitted after the group is removed from the timeline through `ges_container_ungroup`.

Note that group will no longer contain its former children, these are held in children.

Note that if a group is emptied, then it will no longer belong to the timeline, but this signal will **not** be emitted in such a case.

group	The group that was removed from `timeline`
children	A list of Container-s that _were_ the children of the removed `group`
