Randomness groups

[philipborg]

Sometimes you may not want to mix between all piles equally. This would allow the creation of "groups" of randomness in which the randomness applies.

Example: Pile A - 20% in G1 Pile B - 20% in G2 Pile C - 20% in G1, 20% in G2

This would make it so that both pile A and pile B can swap slots that would otherwise be reserved to pile C, but they can't swap between Pile A and B.

This would allow very deep control over card distribution. Probably more than most users need so not super high priority.
