Week 4: Writing classes/17. Football match, part 2: Class Team

Let's continue the implementation by implementing a class that models one team.

So, write a (non-public) class Team with the following properties:
Attribute 'name' (string)
Some attribute to store the players in
A constructor that takes the name as a parameter
Set and get methods for the name
Method addPlayer(Player p), which adds one player to the team
The method printPlayers(), which prints the players in the order of addition as shown in the example below (first the number, then the name):

Example output of players:
7. Pele
8. Ronaldo
