Make some order to the directory structure of the code

There are two modes of writing tests.

The first kind of mechanism relied of writing a test that uses blocking code

and each instance of it is run inside of a separate thread. Beware that your

blocking code must be thread safe to run properly (as is obvious :P)

The other menthod invloves having some knowledge about twisted. The test you

will write will be written in twisted and should implement async style non

blocking architecture.

It is recommended that tests are written using the second pattern and the first

should only be used for runnign tests that have been previously written.
