All routes/views/databases functional
Databases & Models Integrated, Login/Logout/UserProfile Views Working
MVP achieved

Would like to separate out controller concerns: urls/sessions/users.
Would also like to add in and integrate users helper in helper file (name this
user.rb):

helpers do
  # This will return the current user, if they exist
  # Replace with code that works with your application
  def current_user
    if session[:user_id]
      @current_user ||= User.find_by_id(session[:user_id])
    end
  end

  # Returns true if current_user exists, false otherwise
  def logged_in?
    !current_user.nil?
  end
end
