====== moduleLog() ======
wrtc.moduleLog() logs supplied string to the [[https://developer.mozilla.org/en-US/docs/Web/API/Console/log|console log]] and to wrtc.get("log").

wrtc_kit.js logs excessive amount of information to the console log to ease debugging. Your code may also log its activities into the same log(s) using wrtc.moduleLog().

===== Arguments =====
wrtc.moduleLog(module, msg)
  * module - string containing log source
  * msg - string containing the log message

===== Returns =====
Nothing.

===== Example =====
To log that your web client has started you can add to the beginning of your javascript code:
  wrtc.moduleLog('my client', 'started');

The wrtc log fetched by [[ixnx:wrtc:js:api:wrtc:get|wrtc.get("log")]] might contain:

Each log entry contains hour:minute:second.millisecond module: log message
===== Log system errors =====
You are strongly recommended to add this line into your javascript code on the main html page:

  window.onerror = function(e, url, line) {wrtc.moduleLog('SYSTEM', e + ' at ' + url + ':' + line)};

This must be on the //main// html page - it cannot be put into a script include file.

It will log many (but unfortunately still not all) system errors appearing in the javascript log into the wrtc log too.
