title: Is there a way to pass information from the browser to a karma plugin?
body: <p>I'm trying to develop a custom karma plugin reporter, but the docs are quite lacking. I have been able to get most of the plugin working by looking at other karma plugins, but one thing I can't figure out is how to pass information from the browser to the plugin.</p>
  
  <p>I initially tried <code>window.__karma__.log()</code> and using <code>this.onBrowserLog()</code> in the plugin, but then any other karma reporters (e.g. <code>progress</code>) pick that up and also outputs that information, which greatly clutters up the console output from that reporter.</p>
  
  <p>So is there a way to pass messages just to my reporter without other reporters outputting those messages?</p>
