// Cross platform logger to provide a simple and diverse way to start logging,
//      with a specifed level across different platforms Android and WASM and other std desktop targets.

//System:

//<Android>>>: uses android_logger to log messages to logcat.

//<WASM>>> uses console_log and sets a panic hook for detailed messages on browser console.

//<Linux, iOs and macOS>>> uses env_logger for std output logging.

// Level sys: we use log::Level to set the maxium logging level. Defaults to Warn if None is used.
