wip - throttle AC completion, enable congruences over bound bodies

Browse source 
- AC completion which is exposed as an option to the new congruence closure core used roots of E-Graph which gets ordering of monomials out of sync.
- Added injective function handling to AC completion
- Move to model where all equations, also unit to unit are in completion
- throw in first level bound bodies into the E-graph to enable canonization on them.
