sublist method
Returns a new list containing the objects from start inclusive to end
exclusive.
List<String> colors = ['red', 'green', 'blue', 'orange', 'pink'];
colors.sublist(1, 3); // ['green', 'blue']
If end is omitted, the length of this is used.
colors.sublist(1); // ['green', 'blue', 'orange', 'pink']
An error occurs if start is outside the range 0 .. length or if
end is outside the range start .. length.
Implementation
List<E> sublist(int start, [int end]);
