Add a HT that associates ints to nodes

        unsatisfactory use of limit, not fear iteration

- Generalized, Efficient Array Decision Procedures
- Sharing is Caring

        That are used only for propagation

       same for ceiling, floor, floor_to_int

        Avoid useless reasonning:
          - congruence closure
          - simplex
          - instantiations

 Reove the hack about coercions that was just removing problematic axioms

  - Fix Interp when node has already a value
  - Finish intersection of union of interval

    terms can be grouped and scheduling of those decisions freezed

          But not yet really in the SMTLIB format

      Egraph.Ro.t is Egraph.rt and  Egraph.t is Egraph.wt
