Minor nits in example and explanation

[RexJaeschke]

1. My guess is the dates 1012 and 2103 should be 2012 and 2013, respectively.

2. I think the explanation "That cast from SampleCustomer to ICustomer is necessary." is too subtle. This refers to the following initialization:

ICustomer theCustomer = c;

Yes, this involves an implicit conversion from c's type, SampleCustomer, but that is not immediately obvious. How about replacing "cast" with "implicit conversion" or doing some other wordsmithing?

Regards, Rex
