[tournament-org] GroupsInGoDraw

[TobyManning]

I look at the entry and determine if it is possible that A can avoid 
playing anuy of B - H, or if (eventually) a match is inevitable.

If A will have to play 3 out of B-H and 3 others, I just let the 
programme go ahead. The "not same club" will avoid them playing in the 
first round; if they have to play 3 of their mates it s not too 
important if it is games 4-6 or a random 3 games.
