skill (String)

• Write an alternate 3-argument constructor. In addition to passing all 3 arguments to the super class constructor, this constructor should also set the skill attribute to an empty String ("")
• Create a 'getter' and 'setter' method for the skill attribute. The setSkill method must also set the aptitude to 1.
• Create a method called developProficiency that increases the aptitude by 1.
• In this class, implement the hasSkill method works as follows: If the contents of the String argument are equal to the contents of the String in the skill field, return true, otherwise return false.
