COMB_CONV : conv -> conv

SYNOPSIS
Applies a conversion to the two sides of an application.

DESCRIPTION
If c is a conversion such that c `f` returns |- f = f' and c `x` returns |- x = x', then COMB_CONV c `f x` returns |- f x = f' x'. That is, the conversion c is applied to the two immediate subterms.

FAILURE CONDITIONS
Never fails when applied to the initial conversion. On application to the term, it fails if conversion given as the argument does, or if the theorem returned by it is inappropriate.
