Two neighbors have rectangular plots of land A and B. The surveyors give you the coordinates of each. If they overlap, there is a property dispute, and you must return the coordinates of the disputed region. If there is no conflict, return the empty set [].
Suppose A and B look like this.
*--------*
| A |
| *--------*
| | | |
| | | B |
| | | |
| *--------*
| |
*--------*
We will give rectangle coordinates in [xLow yLow width height] format. So
A = [0 0 5 10]
B = [3 2 6 6]
Then you should return rectangle that corresponds to the overlapping region.
C = [3 2 2 6]

I fixed the test suite, which had a problem described by Alfonso below.
Please use isempty() rather than comparing to [] using isequal().
Test suite has been updated to use isempty() to check for [ ].
As always, thanks, Dyuman!
