404 and 500 error pages

[saradotlog]

• Removed 404 and 505 html file in Public folder and Generate a new ErrorsController that inherits from ApplicationController with command rails g controller errors not_found internal_server_error.
• Configure Routes to Handle New Errors Page in config/routes.rb.
• Adjust configuration to turn off the default way Rails will handle errors in the main application.rb file.
• Disable configuration in config/environments/development.rb in order to test things out locally.
• Style, edit and adjust the views within app/views/errors accordingly.
