XD-DENG c072aa771d For Private page, add feature 'take note'

This makes this app much more meaningful. For this feature, a new database table is added. More complicated logics are also needed, for example, we use hash(user ID + timestamp + note contant) as the unique id of each note (it's necessary when we try to delete a note)

Details about This Toy App

There are three tabs in this toy app

Public: this is a page which can be accessed by anyone, no matter if the user has logged in or not.
Private: Only logged-in user can access this page. Otherwise the user will get a 401 error page.
Admin Page: This part is only open to the user who logged in as "Admin". In this tab, the administrator can manage accounts (list, delete, or add).

A few accounts were set for testing, like admin (password: admin), test (password: 123456), etc. You can also delete or add accounts after you log in as admin.
