Start of project

You define this awesome method... and then never use it. You should definitely be using it in ```check_client_folders```.

Also, if you want to make it a bit more useful, add in a optional subfolder, e.g.
```
def get_user_directory(subfolder = nil)
  Rails.root.join("tmp/uploads/#{session[:access_token].to_s}/#{subfolder.to_s")
end
```
or something like that, that way you can do stuff like 
```
Dir.mkdir(get_user_directory("uploads"))
```
