HALF_MK_ABS : (thm -> thm)
STRUCTURE
SYNOPSIS
Converts a function definition to lambda-form.
DESCRIPTION
When applied to a theorem A |- !x. t1 x = t2, whose conclusion is a universally quantified equation, HALF_MK_ABS returns the theorem A |- t1 = \x. t2.
    A |- !x. t1 x = t2
   --------------------  HALF_MK_ABS            [where x is not free in t1]
    A |- t1 = (\x. t2)

FAILURE
Fails unless the theorem is a singly universally quantified equation whose left-hand side is a function applied to the quantified variable, or if the variable is free in that function.
