whether obj1 and obj2 intersect. Two objects
obj1 and obj2 intersect if there is a point
p that is part of both obj1 and obj2.
The
intersection
region of those two objects is
defined as the set of all points p that are part of both
obj1 and obj2. Precondition: the objects are of the same dimension. 
The types Type1 and Type2 can be any of the following:
