Changed the class to extend Spell instead of doing something like...

Heal heal = new Heal();

This makes  sense because Heal is a Spell.

Changed this to extend Spell instead of...

Damage damage = new Damage();

Because Damage is a Spell.

Spell is now extended by Damage and Heal since they both have an 'is-a'
relationship with Spell.
Changed a few variables from protected to private for now as there is no
need for them to be protected as far as I can tell.

Also added a get and set method for the name variable.

Removed the damage and heal variables because this class doesn't require
them.
