Purpose
This composite constraint states a disjunction between two constraints C1 and C2 ( C1 ∨ C2). The satisfaction of the resulting constraint is given by the following truth table: 
  C1     C2       C1 or C2
  --------------------------
  false  false    false
  false  true     true
  true   false    true
  true   true     true

Synopsis
C1 or C2
Arguments
C1 
the left member constraint of the disjunction
C2 
the right member constraint of the disjunction
Return value
A disjunction constraint over C1 and C2
Example
The following example shows how to use the disjunction constraint 
model "Logical constraints"
 uses "kalis"

! Default bounds for all variables
 setparam("KALIS_DEFAULT_LB", 0); setparam("KALIS_DEFAULT_UB", 1)

 declarations
  a,b: cpvar
 end-declarations

 setname(a,"a")
 setname(b,"b")

 writeln(a,b)
 (a >= 1) and (b >= 1) or (a <= 0) and (b >= 1)

 while (cp_find_next_sol)
  writeln("a:", getsol(a), " b:", getsol(b))

end-model
