The reason that Hwk4/Qsort (now named Qsort.V0) fails
the Hwk4/Tests/xQuick.pl test is that it implements
mergeSort, not quickSort!  The new Hwk4/Qsort does pass
the test.

Explanation:  I did not have a working version of Qsort
when I released the specification so I put the solution
from last year's sorting assignment (which implemented
mergeSort using a circular, singly-linked Deque ADT) in
Hwk4/Qsort.  I meant to replace it when I had a working
version, but did not until now.  Both versions pass all
of the tests, but only the new one passes the xQuick.pl
test.
