The documentation regarding creating an assignment override with
`group_id` is made more clear and the prerequisites are better stated.
The group assignments feature and the dependency between
`group_category_id` and `group_id` in the stages of assignment creation
and assignment override creation are explained by a diagram sitting in an
appendix entry at the bottom of the Assignments API documentation page,
Appendix: Group assignments.
The diagram image in the appendix is exported out of the raw .xmind file
in doc/diagrams. You can edit that diagram using the XMind program
(http://www.xmind.net/), it's free to use and cross-platform (JAVA).
