title: need reference to the $log.log call line number
body: <p>When I use angular $log service, all the lines in the console show up with a reference to angular.js:5687 instead of the line where I called the $log.log function.</p>
  
  <p>How can I get a reference to the line where I called $log? Also I have my own service that wraps around $log, how can I reference calls to my service instead of $log?</p>
  
  <p>For example in <strong>Logger.js</strong>:</p>
  
  <pre class="lang-js prettyprint-override"><code> 1) angular.module('MyApp').factory('Logger', function($log){
   2)    return { log : function(msg) { $log.log(msg); };
   3) });
  </code></pre>
  
  <p>And in <strong>SomeCtrl.js</strong></p>
  
  <pre class="lang-js prettyprint-override"><code> 1) angular.module('MyApp').controller('SomeCtrl', function($scope, $log, Logger) {
   ...
  10) $log.log('Hi from $log');     // reference to SomeCtrl.js:10
   ...
  25) Logger.log('Hi from Logger'); // reference to SomeCtrl.js:25
  </code></pre>
