MP : (thm -> thm -> thm)

SYNOPSIS
Implements the Modus Ponens inference rule.

DESCRIBE
When applied to theorems A1 |- t1 ==> t2 and A2 |- t1, the inference rule MP returns the theorem A1 u A2 |- t2.
    A1 |- t1 ==> t2   A2 |- t1
   ----------------------------  MP
          A1 u A2 |- t2

FAILURE
Fails unless the first theorem is an implication whose antecedent is the same as the conclusion of the second theorem (up to alpha-conversion).
