title: Filtering out files in profile results
body: <p>Is there any way to filter out some files from collecting CPU profiles in or just filter them out in CPU profile results?
  That's what I'm talking about (<a href="http://grab.by/so7y" rel="noreferrer">http://grab.by/so7y</a>):

  There's no way to filter the results by filename.
  I tried to find it in Profiles, in Timeline, in Google Web Trace Framework.
  And there is no such thing as far as I see.
  Or maybe it's time to make that feature?
  I think every developer needs it as far as he doesn't want to profile frameworks that he uses.
  I found "black box" feature in FF 27 (<a href="https://developer.mozilla.org/en-US/docs/Tools/Debugger#Black_box_a_source" rel="noreferrer">https://developer.mozilla.org/en-US/docs/Tools/Debugger#Black_box_a_source</a>) but that is for debugging only.</p>
