/**
    @file Debug.h
    @brief Handles different output-levels of errors, warnings, infos and debug informations.

    The COUT(level) macro acts like std::cout, but the output is only performed if the given
    level is <= the soft debug level.

    There are two used values in this file:
     - The hard debug level is used during compiletime. It describes the highest allowed output level.
     - The soft debug level is used during runtime and is the maximum of the three configurable
       output-levels for console, logfile and ingame shell.

    The separation between the three devices is done by the OutputHandler.

    Possible levels are:
     0: Very important output
     1: Errors
     2: Warnings
     3: Informations
     4: Debug information
     5: More debug information
     6: Crazy debug informations

    @example
    COUT(0) << "Very important output" << std::endl;
    COUT(1) << "Error: Something went wrong!" << std::endl;
    COUT(2) << "Warning: There might be a problem." << std::endl;
    COUT(3) << "Info: It's monday" << std::endl;
    COUT(4) << "Debug: x is 1.23456" << std::endl;
