Provides a function "install()" which makes the "mock" module available as "unittest.mock" on Python 3.2 and earlier.

Also advertises a pytest plugin which configures unittest.mock automatically.

If using pytest, simply require this package in your test environment, and unittest.mock will be available.

Otherwise, it must be invoked imperatively:

import backports.unittest_mock
backports.unittest_mock.install()

import unittest.mock
