Example - HTF Values Without 'Security()'

This is an example of how to reference higher timeframe data without the
need for a 'security()' call.

I have attempted to create the function example:

f_insecurity()

with the purpose of wrapping up and pumping out all common relevent HTF
price data that's needed for your everyday indicators in a reliable fashion.

Sürüm Notları:

• Updated to remove potential repainting confusion with:

  security()

• Added ability to toggle the security() comparison overlay on and off.
  

..apologies for any confusion regarding the previous repainting option, it was intended for debugging purposes only at the time of writing.

Cheers - Jay.

Sürüm Notları:

• Cleaned up self-referencing ternary operations - there was no need to reference 'previous' values of self, just 'active' self.
  
• Added 'nz()' conversion checks where they might be necessary.
  
• Removed redundant bar-counting mechanic.
  
• Cleaned up some of the code comments.
