Victor,

I have added the documentation, but for the unit test, there is already a test with the SimpleHTTPRequestHandler class where they specify the cwd attribute, because the code of mdk does not change the behavior, I think it's not needed to write a test.

now, if you think we need a test for this specific case (in fact we only override the constructor of the class and specify the directory parameter), I can write a test, but check the code before.

Thank you.
