checksumable:: (2 methods):
  calculate_checksum()
  is_checksum_correct()


Interface: checksumable  - X-Ref

Interface to apply to all the classes we want to calculate their checksum

Each class being part of @backup_controller will implement this interface
in order to be able to calculate one objective and unique checksum for
the whole controller class.

TODO: Finish phpdocs
calculate_checksum()   X-Ref
This function will return one unique and stable checksum for one instance
of the class implementing it. It's each implementation responsibility to
do it recursively if needed and use optional store (caching) of the checksum if
necessary/possible


is_checksum_correct($checksum)   X-Ref
Given one checksum, returns if matches object's checksum (true) or no (false)
