   * This class is also used to pass the Virtual Filestore (VFS) Implementation to the CFDP
   * handlers so the filestore operations can be mapped to the underlying filestore.
   *
   * It is used by implementing it in a child class and then passing it to the CFDP
   * handler objects. The base class provides default implementation for the user indication
   * primitives specified in the CFDP standard. The user can override these implementations
   * to provide custom indication handlers.
   * @param vfs Virtual Filestore Object. Will be used for all file operations
