 * Constants for bw_trace2's $level parameter
 *
 * - The trace record is produced if the $level passed is greater than or equal to the current tracing level ( $bw_trace_on );
 * - The default value for bw_trace2 is BW_TRACE_ALWAYS
 * - The higher you set the value the more tracing you get.
 * - The testing is NOT (yet) implemented as a bit-mask.
 * - Note: These values are a subset of logging levels in packages such as monolog.
 * - It's not really necessary to have CRITICAL, ALERT or EMERGENCY; ERROR will suffice
 * - See also {@link https://en.wikipedia.org/wiki/Syslog#Severity_levels}
