Create separate page for audio features
An additional page where the user will be directed after logging in was
created. A link to the audio features display page was added to the
aforementioned page. Changes were made to the audio features graphing
function so that the categories are displayed in ascending order (was
random before).

Use secrets.py to generate user secret
Instead of using our own random string generator function, the user
secret is now being generated using secrets.token_urlsafe(). The max
length of the user secret has been increased to accommodate the size of
the 32 byte string.
