 /**

  * The Facade design pattern is often used when a system is very complex or difficult to understand
  * because the system has a large number of interdependent classes or its source code is
  * unavailable. This pattern hides the complexities of the larger system and provides a simpler
  * interface to the client. It typically involves a single wrapper class which contains a set of
  * members required by client. These members access the system on behalf of the facade client and
  * hide the implementation details.
