/*******************************************************************************
This method checks if the i-th item in the result sequences of the input
iterator is in the queue or not. In general, the item may be missing from
the queue because:
(a) it has either been purged, or
(b) it has not been computed yet, or
(c) the result sequence contains less than i items.
Case (a) should never arise: it is the user of the lazy temp sequence that
decided when and how many items to purge, so he shouldn't come back to ask
for an item that has been purged.
In case (c), the method will compute and buffer any input items that have not
been computed already and then return false.
In case (b), the method will compute and buffer all the items starting after
the last computed item and up to the i-th item; then it will return true.
If the i-th item is already in the queue, the method will simply return true.
