unittest2 or unittest

from unittest.case import SkipTest

I think the docs should say that the alias unittest actually refers to unittest2
Depending on which testing library is installed on a users system - unittest or unittest2 the line should change

if the user has just unittest2 and the alias unitest refers to that, its okay

but if the user has unittest and unittest2 then the line should change to

from unittest2.case import SkipTest

what do you think sean?
