=====set_symmetric_difference=====
Syntax:

<code>
    #include <algorithm>
    output_iterator set_symmetric_difference( input_iterator start1, input_iterator end1, input_iterator2 start2, input_iterator2 end2, output_iterator result );
    output_iterator set_symmetric_difference( input_iterator start1, input_iterator end1, input_iterator2 start2, input_iterator2 end2, output_iterator result, StrictWeakOrdering cmp );
</code>

The set_symmetric_difference() algorithm computes the symmetric difference of
the two sets defined by [start1,end1) and [start2,end2) and stores the
difference starting at result.

Both of the sets, given as ranges, must be sorted in ascending order.

The return value of set_symmetric_difference() is an iterator to the end of the
result range.

If the strict weak ordering comparison function object cmp is not specified,
set_symmetric_difference() will use the < operator to compare elements.
