    @enum  priority
    @brief User may use the predefined values or the custom ones, for ex. "normal - 1",
           this type is supposed to be compared relatively and not for equality
    @note  The base type of this enum is u8,
           and lowest will always be the lowest value and highest will be the highest.
           You should use std::greater<qx::priority> as a predicate in ordered containers to iterate them with decreasing priority.
