Public bug reported:

Sikuli 1.0.0 Win7-64

I have a number of methods that I have monkey patched on the Region and
Match objects to extend the API in python and it generally works great.
The one issue is that above(), below(), left(), right(), nearby() and
offset() do not return a proper Region object.  I think example code is
the easiest way to explain, let me know if you have questions:

<pre>
# define function to be added to Region object as a new method
def monkey_patch(self):
    popup(str(self))
    return self

# Add the method to the Region object
Region.monkey_patch = monkey_patch

# Create a region object at the center of the screen
regionCenterScreen = Region(SCREEN.w/2, SCREEN.h/2, 5, 5)

# printing the class name shows that this is a Region object
print "regionCenterScreen: %s" % regionCenterScreen.__class__.__name__

# printing the class name of the object returned by the left method is also a Region so it should have the same methods and 
# attributes as the original object
print "regionCenterScreen.left(5): %s" % regionCenterScreen.left(5).__class__.__name__

# print the difference between the method/attributes of the two objects
# This should be an empty set, but instead it's actually pretty long
print set(dir(regionCenterScreen)) - set(dir(regionCenterScreen.nearby(5)))

# This works
regionCenterScreen.monkey_patch()

# This throws AttributeError
regionCenterScreen.left(5).monkey_patch()

# This works
Region(regionCenterScreen.left(5)).monkey_patch()
</pre>
