Say you want to add a keyword instance method into Smalltalk's built-in
Integer class called ``max:'', which returns the maximum value between
the Integer instance to which the method is applied and the argument.
For example, the code ``3 max: 5'' should return 5, while ``6 max: 2''
would return 6. Write the definition of this method to be added to the
Integer class.
max: other self > other ifTrue: [ ^ self ] ifFalse: [ ^ other ]
