Turn and Weave

This is a 4-person call. The "Turn" is a Trade or Touch 1/2. The rules for this, and the rules for the Weave, are complex.

I recommend thinking of this in terms of 4 actions — "Touch, Trade, Extend, and Weave".

Touch if necessary until at least some people are in a miniwave.
Those in the miniwave(s) trade.
Extend if necessary until everyone is in miniwaves.
Weave.
