//Purpose: This is the abstract class that provides the template for ContactsAcquaintance, 
//ContactsBusiness, and ContactsFriend. I choose to use an abstract class as an inheritance model because 
//I know a Contact will never be instantiated that isn't a Acquaintance, Business, or Friend.

	//The attributes for this class are those shared by all types of contacts.

	public ContactsContact(String name, String phoneNo) {
		this.name = name;
		this.phoneNo = phoneNo;

	//Public setter functions that can be called by all types of contacts.
	public void setName(String name) {
		this.name = name;
