@Override
	public char next() {
		return super.next();
	}
Increments the current index by one and returns the character at the new
index. If the resulting index is greater or equal to the end index, the
current index is reset to the end index and a value of DONE is returned.
NOTE: For this extended class, we are not modifying the behavior of this
method, but want to caution against its use, except for when desiring the
specific behavior of not having the returned character added to the
genericizedString. Suggested use is to use peek() and next() when not
wanting to add the character, but to use getAndIncrement() when wanting
to add the character.

@return the character at the new position or DONE
