I realized that I should declare I file that I am using from another project.
Contents of the file follow the break.
Here it is:

# Rectangle container with collision methods
#
# @author Henry Mclaughlin
#
# This is a generic rectangle container that has some
# collision methods, a couple of boolean methods, and
# properties for many points in itself.
#
# It has the following collision methods:
#
# \li Check overlap
# \li Clamp in
# \li Clamp off
#
# It has the following boolean methods:
#
# \li Union
# \li Intersection
#
# It has properties for the following points:
#
# \li Left, right, top, and bottom edges (single coordinate)
# \li Top-left, top-right, bottom-left, and bottom-right corners
# \li Left, right, top, and bottom edge mid-points
# \li Horizontal center and vertical center (single coordinate)
# \li Center point
# \li Width and height (individually)
# \li Size
#
# When a Rect's corners are modified, it moves without
# changing size.
#
# \note There are a \e lot of methods here that are not
# documented. This is because you are meant to
# use the properties, which \e are documented.
#
# \todo Implement clampIn()
# \todo Implement clampOff()
# \todo Implement boolean functions
# \todo Implement overlapList(), overlapAny(), and overlapAll()
#
class Rect(object):
##
# Constructor
#
# Params are complicated...
#
# \todo Document the parameters
# \todo Proper error messages
