    \class Macros::MacroEvent
    \brief Represents an event in a macro

    An event stores information so it can be replayed. An event can be:
    \list
    \o menu action
    \o key event on an editor
    \o find/replace usage
    \o ...
    \endlist

    The information are stored in a map of QVariants (using quint8 for keys).
