Removing directory contained a read-only file. 'rmtree' function of 'shutil' python library fails when it tries to remove read-only file. I found a solution in this articles. ~http://stackoverflow.com/questions/21261132/shutil-rmtree-to-remove-readonly-files~ (read) ~https://bugs.python.org/issue19643~ (read) ~http://stackoverflow.com/questions/1889597/deleting-directory-in-python~ (read)

The solution is a workaround unfortunately.

TODO. Need to refactor '_removereadonly' function. I need to understand more about how this works.

I thought about the need to refactor 'remove_readonly' function and I decided that it isn't nessecary.

DONE.
