'''Init by specifying a name and a set variables the constraint is over.
Along with a list of satisfying assignments.
Each satisfying assignment is itself a list, of length equal to
the number of variables in the constraints scope.
If sa is a single satisfying assignment, e.g, sa=satisfyingAssignments[0]
then sa[i] is the value that will be assigned to the variable scope[i].
Example, say you want to specify a constraint alldiff(A,B,C,D) for
three variables A, B, C each with domain [1,2,3,4]
Then you would create this constraint using the call
c = TableConstraint('example', [A,B,C,D],
[[1, 2, 3, 4], [1, 2, 4, 3], [1, 3, 2, 4],
[1, 3, 4, 2], [1, 4, 2, 3], [1, 4, 3, 2],
[2, 1, 3, 4], [2, 1, 4, 3], [2, 3, 1, 4],
[2, 3, 4, 1], [2, 4, 1, 3], [2, 4, 3, 1],
[3, 1, 2, 4], [3, 1, 4, 2], [3, 2, 1, 4],
[3, 2, 4, 1], [3, 4, 1, 2], [3, 4, 2, 1],
[4, 1, 2, 3], [4, 1, 3, 2], [4, 2, 1, 3],
[4, 2, 3, 1], [4, 3, 1, 2], [4, 3, 2, 1]])
as these are the only assignments to A,B,C respectively that
satisfy A+B=C.
