/// <summary>
/// This example uses the Bridge Pattern to separate high-level abstractions from implementation details.
/// We have a Farmers Market, where different types of vendors process payments using different
/// types of Payment Processing services, including credit cards and gift cards.
/// The "Bridge" is the has-a relationship between vendors and their payment processors.
/// Any FarmersMarketVendor has an object that implements the IProcessesPayments interface.
/// Because every concrete FarmersMarketVendor is programmed to work with the high-level IProcessesPayments interface,
/// the vendor logic can be extended independently of the implementations of the Payment Processors. Likewise,
/// the implementors of IProcessesPayments know nothing about the context in which they are used, and can be treated like a plugin.
/// in fact, they can be used in many other contexts, so they've been extracted to the RealisticDependencies class library.
/// By using object composition in this way, we avoid creating an exponential explosion in a potential
/// subclass hierarchy for specific vendor-processor combinations.
