    \brief Represents a macro, which is more or less a list of Macros::MacroEvent

    A macro is a list of events that can be replayed in Qt Creator. A macro has
    an header consisting of the Qt Creator version where the macro was created
    and a description.
    The name of the macro is the filename without the extension.
