Min/Max range of individual players should include the range of groups. (e.g., if the Max exposure for a group is 40%, all the players in that group should have max exposure set to 40% or greater)

Use Stack Max to determine how many players from each group to include. This can be used to do things like make sure all lineups include at least one of a group of players. The default is to try to include all players in a group in all lineups.
