Updated layout so that it has a navigation bar.

Navigation bar was copied and pasted from
[the sinatra skeleton for the DBC phase 2 mock assesment](http://cl.ly/0v0G1I273W3o)
Added sign-in view and route

Added sign_in.erb to views folder, and copied the sign_in view from
the sinatra skeleton from the phase 2 DBC mock assesment.

Added users.rb controller.

Added get method to get '/users/sign_in' so we can see the veiw.
Added sign_up.erb view and signup gets route

Added sign_up.erb view which is our sign-up sheet.
Added '/users/new' route to display our sign-up sheet.

It is an exact copy of the sign-in sheet. We will refactor it later.
Added Bcrypt to encrypt password and Validations to user model

In the user model, we deciced that we wanted our passwords to be
secure. So we copied and pasted the user bcrypt features from the
user model in this sinatra skeleton. http://cl.ly/0v0G1I273W3o
We have not tested this yet.
Added users routes and sessions routes to users.rb

We copied all of the users controller code from the [sinatra
skeleton ](http://cl.ly/0v0G1I273W3o). We now have the ability to
add sessions, sign up users and drive our sign-in and sign-up views.

We have not tested this.
Replaced sign_up view with code from sinatra skeleton

Replaced our sign-up veiw with the sign-up view from http://cl.ly/0v0G1I273W3o
Since we added all of the driver code in our user veiw from the
aformentioned skeleton, we predict this view will no longer give us errors.
Testing this now.
Login, logout, and sign-up features complete

We basically merged the login-logout functionality from http://cl.ly/0v0G1I273W3o
into our survey project.  We can now sign up, sign in, and sign out.

Basically we the login id from a unique e-mail to a unique username.
This is why you see a lot of lines changing the e-mail to the username.

We also updated some migrations that we had forgotten to add 's' to, which
meant the activerecord associations were not working right.

The rest of it is a straight merge from the aformentioned sinatra
skeleton.
Bugfixed question has many answers association

Fixed our question model so that it has many answers. It did not make
sense for a question to have many questions. We are not zen masters, so
we do not care to ponder the circularity of that error.
Merge branch 'master' of https://github.com/tararoys/SurveyDBC
