Minor update to EC++ Errata

In response to the latest reprint request from Addison-Wesley, I updated
the errata list for EC++. Below are the latest changes (in my usual "sort
of HTML" format).

declared private in MyPerson, because clients
should not be able to call them. They're just an
implementation detail of the class.

7/21/04 am 179-180 Another way to deal with the need to downcast if you can't
redefine allAccounts or BankAccount is to declare
something like NewBankAccount as a sibling class to
SavingsAccount and CheckingAccount, then adopt a policy of
deriving new classes only from NewBankAccount. You'll
still have to downcast from BankAccount to Savings-,
Checking-, or NewBankAccount, but once you're in
NewBankAcount, you can use a virtual creditInterest.
