Controllers Basic2

Create a new model called User with the following fields

first_name
last_name
email_address
password
Create form in /users/new (users controller, new method) where someone
can create a new user account.  Validate the form and display necessary
error messages if the form is invalid or display a success message that
says the form looks valid.

Make sure that the information gets posted to /users.  The create
method in the Users controller should process the information, pass
necessary information back to appropriate methods/views and if
validation worked, create a new record in the users table.

For this assignment do not use Partials and do not worry about using
rail's form helpers.
