Back End working off the version we had last week

What’s been done?
MAIN:
Checks if you have a barcode and name in local storage, if you do then
takes you str8 to page 1 (barcode page) , if no, shows you splash
screen.

signupform
- POSTS form data to server
- Retrieves barcode
-  Saves to localStorage the barcodeNumber and userName
-Takes you to page 1

page2 (perks page) now pulls and displays all perks. If you want to
print out more data, check the options I’ve commented righ above the
populatePerks print line.
