Changed port to 5000
Added a members schema which is basically a table with two fields: a members ID and their member Type. This table will help when validating logins so that we dont have to check the provided credentials against all user tables in the DB just to establish the members validity
Added dummy thank-you data to be displayed on the page where a new user must create their profile. Also added dummy styling for this info
Added field to display error when users provide bad login credentials
Added a members script to the model layer. This will handle enrolling new users into the members table and also checking for the validity of login details
Updated the authenticate function to first validate the credentials against the members table, and proceed based on the results
