Grouped lists. Equal consecutive elements are grouped

Grouped lists work like regular lists, except for two conditions: * Grouped lists are always finite. Attempting to construct an infinite grouped list will result in an infinite loop. * Grouped lists internally represent consecutive equal elements as only one, hence the name of /grouped lists/. This mean that grouped lists are ideal for cases where the list has many repetitions (like '[1,1,1,1,7,7,7,7,7,7,7,7,2,2,2,2,2]', although they might present some deficiencies in the absent of repetitions.
