 The output of this code would be \pigOut{brett}.
+You access methods the same way as your would class properties except you include the parenthesis.
+You may also notice a reference to a variable \pigVar{this} in the method definition.
+This special variable is used within methods to refer to the object that the method belongs to.
+So using \pigVar{this} within the method \pigVar{printName} is similar to using the variable \pigVar{p} to access
+the specific instance that that method belongs to.
