Fib Retracement

I've re-created the fib retracement tool as an indicator and this is as close as I can currently get to matching the built-in fib retracement tool.

Why did I make this? For custom labels for every fib retracement level.

Caveats to this vs the built-in tool are:

• the "Save as Default" doesn't appear to work (I believe this is due to the interactive/confirm based settings)
  
• copy and paste to another chart is locked into the price of source location
  
• when dragging the points of retracement the tool/indicator disappears
  

Hopefully some can find usefulness in this code or it's functionality.
