Returns a Sequence containing all elements of self between the positions 'startIndex' and 'endIndex'.

Expression	Result
Sequence{'a', 'b', 'c', 'd'}->subSequence(2, 3)	Sequence{'b', 'c'}
Sequence{'a', 'b', 'c', 'd'}->subSequence(4, 4)	Sequence{'d'}

Returns a smaller collection from start to stop.

subSequence(<start>, <stop>)

Please note that the index number is 1-based.

Example:

Sequence{1..20}->subSequence(10,15)

The expression above will return numbers 10, 11, 12, 13, 14, and 15.

If you supply index values outside the source collection, the result collection will be empty.
