Combine rule groups

[cody-scott]

Combine rule groups to use composites. Attach output option to groups too.

Idea is to match all from one set and any from a second set to get output.

Essentially rule groups that take rule groups as inputs.

unsure how to prevent circular references, or does that even matter?
If using a list, execute in order of the list, need groups that call another group to be defined after that group.

If group B uses group A in rule, then:
[groupA, groupB]
