Joe Gregorio originally `posted `_ about Sharded Counters for Google Appengine.

This is like a downloadable gist::

    from sharc import Counter

    assert not Counter('A').exists()

    Counter('A', initial_value=5, shards=5)

    assert Counter('A').exists()

    Counter('A').increment()

    Counter('A').decrement()

    Counter('A') + 2

    Counter('A') - 2

    assert Counter('A') == 5

    Counter('A').shards = 10

    Counter('A').delete()   # .delete_async()

    assert not Counter('A').exists()

- Added decrement

- Increment and decrement variable deltas (default=1)

- Set initial value of the counter (default=0)

- Set initial value of the num of shards (default=20)

- Added delete()
