duplicate rref algorithm
http://code.google.com/p/sympy/issues/detail?id=1850
I'm looking at the two functions and, as I understand them so far, they are
using almost identical algorithms. The largest difference that I see

I've updated the geometry branch by cleaning up the intersections method
and making the encloses method (previously my inside method) more robust.
It still needs good testing.

We need a general way to describe and test for singularities. In particular
Wild('a')*oo should be recognisable as usually singular.

This cases() function is a very nice idea. As to cancel(), this this a
common design pattern to make a function do one thing at time. cancel() can

But the whole point of cancel is to cancel out common polynomial factors.
Otherwise, it is useless.
Perhaps the functionality you mention could be

The example of the last, when the limit of series's terms is analyzing.

On the other hand simpify() should go the other direction and be feature
full. This is not the case currently as simplify() == cancel() + eps. I
