(NEW) Module "retry"

Browse Source 
(NEW) Illustrative classes:
      - App: simulates a production application
      - BusinessOperation<T>: abstraction over any operation that can
        potentially fail
      - FindCustomer <: BusinessOperation<String>: illustrative
        operation that can throw an error
      - Retry <: BusinessOperation<T>: transparently implements the
        retry mechanism
      - Several "business" exceptions:
        - BusinessException: top-level
        - CustomerNotFoundException: can be ignored
        - DatabaseNotAvailableException: fatal error
(NEW) .puml and .png for UML
