"""
Helper for looping over sequences, particular in templates.

Often in a loop in a template it's handy to know what's next up,
previously up, if this is the first or last item in the sequence, etc.
These can be awkward to manage in a normal Python loop, but using the
looper you can get a better sense of the context.  Use like::

>>> for loop, item in looper(['a', 'b', 'c']):
    ...     print loop.number, item
    ...     if not loop.last:
    ...         print '---'
    1 a
    ---
    2 b
    ---
    3 c
