    \class Macros::Macro

    \brief The Macro class 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 \QC. A macro has
    an header consisting of the \QC version where the macro was created
    and a description.
    The name of the macro is the filename without the extension.
