Some dumb tests and a fix

[obiwanus]

Added tests for py26, py27 and py32.
Fixed the calculation of rate in format_meter.

Thanks for the impressive work!

I tried to run the tests and they failed. I don't know exactly why.

Here's the output:

Those are very strange errors, and googling doesn't help much. Just tried to run the tests on another Ubuntu machine (I use Debian myself) and they passed. What I can suggest is:

1. Create a virtualenv manually, install pytest into it and run py.test from it - if it fails, then one of the problems is in pytest
2. If you have had tox previously installed, try to update it: sudo pip install -U tox
3. Finally, you can create a fresh virtual machine and try them there

Obviously the problem is in the environment, which doesn't like either tox or pytest.
