Server and Buging

In this iteration we will finish our server side including establish connection to FireBase, and fixing the last bugs we have. This might be last iteration, we have to finish on time so we will have enough time to the finish report. As well as fixing the running on device bug we have. We need to deal with the important features we need, like deleting files after we send them. Also, we need some data structure to save the file we have on server

Testing

Test	Expectation Result	Result
Handle multi connections	Server know how to respond for more the 1 client	OK
Server get files properly	Get files with the new name and the same data	OK

Iteration Conclusions

Project is ready, still few test remain. Next iteration will be some featuring and code reflactoring

Next Iteration
