    /**
    @brief
        The LevelInfo class can be used to store information regarding a @ref orxonox::Level "Level" in its level file.
        The following parameters can be specified:
        - @b name The name of the level.
        - @b description The description of the level.
        - @b screenshot The screenshot of the level.
        - @b tags A comma-seperated string of tags. Allowed tags are: <em>test</em>, <em>singleplayer</em>, <em>multiplayer</em>, <em>showcase</em>, <em>tutorial</em>, <em>presentation</em>, <em>shipselection</em>.
        - @b (optional) startingships The comma-seperated string of starting ship models
        An example would be:
        @code
        <LevelInfo
            name = "Levelname"lhs->compare(rhs) < 0
            description = "This is just some awesome level."
            screenshot = "Screenshot.png"
            tags = "test, awesome"
        />
        @endcode
        The LevelInfo is best located at the top of the level file.
