Berthold Stoeger f9fe6d759f undo: split out EventBase class
All event-based commands will work on a dive computer and
need to replot the profile, etc. Therefore, in analogy to
the dive-list commands create a base class with two virtual
functions undoit() and redoit() that must be defined in the
derived classes that do the actual work.
