Changes

== Adding Actions and Outlets ==

When the user enters a temperature value into the text field and touches the convert button we need to trigger an action which will perform a calculation to convert the temperature. The result of that calculation will then be presented to the user via the label object. The Action will be in the form of a method which we will declare and implement in our View Controller class. Access to the text field and label objects from the view controller method will be implemented through the use of Outlets.
