CountMinSketch
==============

This is a minimalistic
`Count-min Sketch <http://en.wikipedia.org/wiki/Count%E2%80%93min_sketch>`_
for Python, featuring some cool things like:
- Being able to count anything that is hash-able by python (numbers, strings, tuples, inmutables, duck-typeds, etc.).
- Tests
- No dependencies
- No foreign languages, just 100% python.
