//**** client code that does not need to be changed ***
/*
* //LDAF007 - THE CORE
* Notice that regardless if you pass in BookStoreA or BookStoreB into the method above, this client code does
* not need to be changed since it will get the correct advertiser automatically using the internal logics
* within the factories. It is the factories (BookStoreA and BookStoreB) that determines which advertiser to produce.
* The same goes for choosing which book distributor to produce.
*
* The benefit of the Abstract Factory pattern is that it allows you to create a groups of products
* (the distributors and the advertisers) without having to know the actual class of the product being produced.
* The result is that you can have client code that does not need to be changed when the internal logic of
* the factories on which product to produce changed.
