Admin login:
The program has a static password common to all admin entries.

Expected:
Admin profile database to be made. Create "Login" and "New user?" option in the admin section.
Under Login- ask admin to enter username and password, check database to validate the same.
Under "New user?"- ask new admin to enter a username and password. Check database for repetition of username, if repeated ask user to enter a new username. Add the new username and password onto the database.

Optional: Create an algorithm that checks and displays the strength of a password when a new admin is creating a profile.
Strength criteria: Must have at least 8 characters. Lowercase, Uppercase, at least 1 Special character and at least one number in it.
Could also include an option to generate a strong password for the admin.
