<div class="block">Test validating the order preserving properties of join algorithms in
<code>ExtendedEnumerable</code>. The correctness of the
join algorithm is not examined by this set of tests.
<p>To verify that the order of left/right/both input(s) is preserved they
must be all ordered by at least one column. The inputs are either sorted on
the join or some other column. For the tests to be meaningful the result of
the join must not be empty.
<p>Interesting variants that may affect the join output and thus destroy the
order of one or both inputs is when the join column or the sorted column
(when join column != sort column) contain nulls or duplicate values.
<p>In addition, the way that nulls are sorted before the join can also play
an important role regarding the order preserving semantics of the join.
<p>Last but not least, the type of the join (left/right/full/inner/semi/anti)
has a major impact on the preservation of order for the various joins.</div>
