Fixed current one to many's
Merge branch 'devss'
Finished both logging in and registering, just have to add some loading things to make it look nicer and I also need to finish persistance. I haven't finished the singleton (You can't get any information from logging in yet)

Fixed startDate/endDate inversion in loginAsync. Charts update based on class selected
