      Version-Log:
      
      source/pnumsolver.ml:
      source/pnumsolver.mli: [new files]
         Implements a numeric solver based on Polka.
         (not plugged yet).
      
      source/rnumsolver.ml:
         Reimplement split_store so that it uses 2 calls of add_constraint
         instead of doing the work twice inside split_store (in order to avoid code
         duplication).
      
         Also, whenever delayed constraints becomes of dimension 1, when a
      add_constraint
         binds a value, add them to the store.
      
         Enhance error msgs whenever int and float are mixed in the same lucky
         expressions.
      
      source/rnumsolver.ml:
      source/ne.ml:
         rename Ne.resolve_triangular_system into get_subst_from_solved_system
         and move it into rnumsolver. The rational is that is was not
         really solving any triangular system: the system ougth to be already solved.
      
      source/parce_env.ml:
         Set the max_float to max_int, otherwise, the conversion into polka rational
         fails...

      Version-Log:
      
      source/solver.ml:
      source/rnumsolver.mli,.ml:
      source/constraint.ml,.mli:
         Split the Constraint.t type into t and ineq where
         inequalities are in ineq. The rational is that most
         operations on constaint.t are actually done on ineq.
         This change therefore avoid pattern like
         <<_ -> assert false>> and let the type checher check
         that sort of things.

      source/ne.ml,mli:
      source/value.ml,mli:
         (new files) put everything that is related to normal expressions
         and values in thoses 2 new modules.
      
      source/ne.ml,mli:
      source/gne.ml,mli:
         Make the normal expressions and the guarded normal expression abstract.
      
      source/solver.ml:
         also fix a bug in the previous change (forgot to try make test ...)

      Version-Log:
      
      Prepare things for the next change (which will try to handle equalities
      smartly).
      
      source/solver.ml:
      source/rnumsolver.ml:
         atomic_formula do not need both < and > (ditto for <= and >=).
         Indeed, I just need to take the opposite, and everything is fine.
         One advantage is that there are less cases to handle. But the key
         advantage is that it make the representation of constraint normal,
         which is important at least when I will try to detect equalities.
      
         Also add a subst list and constraint list fields to the store
         that will ebe used in the forthcoming change. They will resp.
         be used for removeing a dimension when an equality is encountered
         and to delay constraint with more than one variable.
      
      source/constraint.ml,mli: (new files)
         Move there from formula.ml everything that is related to the internal
         representation of constraints.
      
         Also change the name of atomic_formula to linear_constraint, which is
         more informative.
