12.15.1. Exercise [45 min]

Give the Animal class the ability to get and set the name and color. Be sure that your result works under use strict. Also make sure your get methods work with both a generic animal and a specific animal instance. Test your work with:

my $tv_horse = Horse->named('Mr. Ed');
$tv_horse->set_name('Mister Ed');
$tv_horse->set_color('grey');
print $tv_horse->name, ' is ', $tv_horse->color, "\n";
print Sheep->name, ' colored ', Sheep->color, ' goes ', Sheep->sound, "\n";

What should you do if you're asked to set the name or color of a generic animal?
