Summarize data

Please, check my code!
I forgot to include some kind of readme.st. To test custom command:
python manage.py summarize [date YYYY-MM-DD] [--nodeletion]
If you pass no parameters it summarizes current date minus 15 days (single day and no a 15-days period)
It's a change I did on Sept. 5.~~I can't remember why I did it because I was starting in both the company and the project. I just wanted to make it run~~. :(
I tried to symlink to /home/produser/rbkeys-okapi-web.ini but it didn't exist. As a temporal solution, I copied both rbkeys-okapi.ini and rbkeys-okapi-dev.ini to my home folder and renamed them to rbkeys-okapi-web.ini and rbkeys-okapi-web-dev.ini to make it go. I probably thought that as I was developing, I should start using the "dev" one. That explains this change.
Both rbkeys-okapi-web.ini and rbkeys-okapi-web-dev.ini have the same content. I also have rbkeys.ini pointing to rbkeys-okapi-web-deb.ini
I'll try to leave it as it was or as it should.
