Bool is the reified truth of at least one of the constraints ConX or ConY being true.
- Reified truth value of the constraint
Equivalent to BX $= (ConX), BY $= (ConY), Bool #= (BX + BY #>= 1)
The two constraints are reified in such a way that Bool reflects the
truth of at least one being true. ConX and ConY must be constraints that
have a corresponding reified form.
