+Various non-built-in utility functions and definitions for Py2

+For example:

+    >>> # without "from __future__ import division"
+    >>> from past.utils import old_div
+    >>> old_div(3, 2)    # like 3/2 in Py2
+    0
+    >>> old_div(3, 2.0)  # like 3/2.0 in Py2

+    This requires a bit of explanation: the basic idea is to make a

+    we also need to make sure that we downgrade the custom metaclass
+    for one level to something closer to type (that's why __call__ and
+    __init__ comes back from type etc.).
+
+    This has the advantage over six.with_metaclass of not introducing
+    dummy classes into the final MRO.
