/*
    Service Contracts are collections of operations or methods,
    which take parameters and return values.
    They provide interface for those methods.

    Data Contracts are parameters taken by service contracts and
    values that they return

    Service is a class that contains implementations of those methods
    that we want to be available for our client.

    Service Contracts + Data Contracts + Service = Service Host

    To be able to call Service, ClientApp needs to have a proxy,
    which is a chunk of code that runs and lives in the client application process,
    exposes the interface that is the same interface as the service.

                    COMMUNICATION PIPE
    CONSUMER => (PROXY => SERVICE CONTRACT) => SERVICE

    Configuration defines all the aspects that define the nature of communication pipe,
    between client and server side.

    Configuration consists of three main parts:
    a) Endpoints (analogy to a phone call)
        - Address (number to dial)
        - Binding (speaking the same language)
        - Contract (subject to talk about)
    b) Behaviors - definition of how the service handles a call once it comes into the service
    c) Bindings - definition of details - how big can your messages be, what kind of security are you using
