support phi-loops
The new support for butterflies and relay forking is great, but it would be awesome to have the option of creating course variations with phi-loops as well. These seem to be more commonly used by planners than traditional butterfly loops these days.
(Basic diagram of a phi-loop here, although note you can also include controls on the diagonal between 1,6 and 3,7: http://news.worldofo.com/wp-content/uploads/2010/01/philoop-300x226.jpg)

This can be created using just a normal forking (variation), doesn't it? I have done it several times, even with a map flip on one of the butterfly wings, making it difficult to mess up the control order for the runners.
