Function mhlog::init

pub fn init<T: ToString>(
    level: Lvl, 
    prog_name: T, 
    write2file: bool
) -> Result<(), LogError>

Initialize mhlog. It is not necessary to do initialization before calling the logging macros. Default logging level before initialization is performed is Lvl::Important.

Initialization can only be done once. If called more than once nothing happens.

During initialization the logging level is set, and if write2file argument is true the log file is opened. prog_name argument is used to name the log file: ~/.log/<prog_name>.log.
