TRUE_FALSE_REFL_CONSEQ_CONVConseqConv.TRUE_FALSE_REFL_CONSEQ_CONV : directed_conseq_conv
Given a term t of type bool this directed
consequence conversion returns the theorem |- F ==> t
for CONSEQ_CONV_STRENGTHEN_direction, the theorem
|- t ==> T for CONSEQ_CONV_WEAKEN_direction
and |- t = t for
CONSEQ_CONV_UNKNOWN_direction.
