Create an inference table for processing a new goal and instantiate that goal in that context, returning "all the pieces".

More specifically: given a u-canonical goal arg, creates a new inference table T and populates it with the universes found in arg. Then, creates a substitution S that maps each bound variable in arg to a fresh inference variable from T. Returns:

  • the table T
  • the substitution S
  • the environment and goal found by substitution S into arg
