  Learning:
  * Using the super keyword to access the super class constructor
  * Using the super keyword in toString() to implement some 
    behavior in the parent (returns String representation of the
    parent attributes and some behavior in the child). Builds on
    String created by the parent and adds the attributes of the
    child.
