COLLISION_GROUP_NONE is the default collision group. These collide with everything. Other collision groups have special rules. E.g. COLLISION_GROUP_DEBRIS doesn't collide with other COLLISION_GROUP_DEBRIS.
In the end, collision group is simply an id. The behavior of it is controlled by the mod's implementation of gamerules' ShouldCollide() function. In there you specific whether any pair of collision groups collides with each other. So you can make it do anything you want. If you don't want an entity to have any collision, you set the solid flag FSOLID_NOT_SOLID.
