Fix profile management #17
Description
For the live/deployed version of HearSay's back-end, profile management had to be removed (commented out) because it was only designed for local system user (single user) and was not a part of the project's MVP. To re-implement this (great!) feature, one should look into using cookies to store a user's profile data on their browser, and to make handling the creation of a profile an independent action that a single thread carries out for a user.
