<ConsistencyModule:> table(+Vars, ++Table)

   Constrain Vars' solutions to be those defined by the tuples in Table.

Arguments
   Vars                Collection of N (domain) variables or integers,
 or a collection of a collection of N (domain) variables or integers.
   Table               Collection of tuples, each of which is a collection
 of N integer values

Type
   library(gfd)

Description
   table is an extensional constraint or user defined constraint, i.e.
   the solutions for the each posted constraint is explicitly defined within 
   the constraint. Each table constraint specifies the solutions to N
   variables, with all the solutions for this constraint specified in Table,
   in the form of tuples, each of N values that is one solution to the
   constraint. 

   Vars represents the variables that are to be satisfied for this
   constraint. It can be one collection of N variables (or integers),
   or a collection of a collections of N variables (or integers), if
   the constraint is to be satisfied by more than one collection of 
   variables. Posting the constraint with multiple collections of 
   variables is logically equivalent to posting individual table
   constraint with the same Table for each collection, but should be
   more efficient as the same Table is shared by all the collections.

   ConsistencyModule is the optional module specification to give the 
   consistency level for the propagation for this constraint: 
   gfd_gac for generalised arc consistency (domain consistency).

   This constraint is known as in_relation in the global constraint catalog, 
   with the allowance for multiple collections of variables taken from
   SICStus Prolog's table/2 constraint. This constraint is implemented in
   Gecode as the extensional() constraint with the variant that takes a
   TupleSet as an argument.

[eclipse 10]:  table([[5,3,3],[5,2,3]],  
                     [[](5,2,3),[](5,2,6),[](5,3,3)]).         % succeed

[eclipse 11]: table([5,3,2], [[](5,2,3),[](5,2,6),[](5,3,3)]). % fail

[eclipse 12]: L = [A,B,C], table(L, [[](5,2,3),[](5,2,6),[](5,3,3)]), 
        labeling(L), writeln(L), fail.
