current rule structure. with new class design

[gagoar]

Issue Reference: progress on #213

Description

This PR changes the point of contact between every part of the system and the rules.

Motivation and Context

I've unified the Rules interactions with the system into 2 classes. that will serve us as a simplified API.

Rules and MatchingRules will allow us to work on them to bring the new rules structures in place without creating confusion or changing (much) actions and the index while we rework things.

How Has This Been Tested?

unit tests.
