-// These are commands that edit individual fields of a set of dives.
-// The implementation is very OO-style. Out-of-fashion and certainly
-// not elegant, but in line with Qt's OO-based design.
-// The actual code is in a common base class "Command::EditBase". To
-// read and set the fields, the base class calls virtual functions of
-// the derived classes.
-//
-// To deal with different data types, the base class is implemented
-// as a template. The template parameter is the type to be read or
-// set. Thus, switch-cascades and union trickery can be avoided.
