      YUI's Y.log statement supports additional options which we can make use of to ease our debugging woes.

      See http://yuilibrary.com/yui/docs/api/classes/YUI.html#method_log:

      (msg, cat, src, silent)

      We can filter on the logLevel (

      1. debug
      2. info
      3. warn
      4. error

      See http://yuilibrary.com/yui/docs/api/classes/config.html#property_logLevel

      And we can exclude and include various statements by the src:

      YUI_config.logInclude = {
      		 
        'moodle-core-example': true
      		 
      };
      		 
      YUI_config.logExclude = {
      		 
        'moodle-core-example': true
      		 
      };

      See:

      We should then encourage people using Y.log in their code to add both priority and src so that the relevant log lines can be filtered at will.
