Hello!
First of all, great job! I just played with the SwiftyDropbox on API v2 for a few days and I must say it's really easy to get it all working.
I have one question though.
What would be the best way to send multiple files and keep track of that progress? Since at the moment I'm calling client.filesUpload(path: "\(path)/\(file)", body: data).response { response, error in ... in a for in loop. In some way it caches all the files (since the for in is done in a second) and sends them after each other to dropbox. This way it's really hard to track the progress, since it will give a success after every file. Of course I can put a counter to it and add it every success, but that just looks messy 
Also, can we expect a function to send multiple files as well in the future?
Thanks for the great API!
