shPerformance (fps, latency, memory - LDB)

This is an extremely light-weight data broker addon that displays the following:

NOTE: You must have a data broker display addon in order to enable this addon. I recommend Docking Station. Changing the fonts of the tooltips is handled via a tooltip addon. I recommend TipTac

• Frames per second (fps)
  
• Latency (ms)
  
• Addon memory usage
  

I was completely baffled when I saw some coding of other author's data broker addons that displayed this information. My goals in creating this addon are:

• Make the code as efficient as possible and to maintain < 30kb of memory usage
  
• Be visually appealing and easy to read
  
• Be updated in real time via the tooltip AND data broker text
  
• Display relevant data that is important (no fluff)

I hope I have reached all these goals and I welcome any feedback!

If you are experiencing ANY type of frame "stuttering" then I recommend changing the newly added boolean value in the CONFIG section of shPerformance.lua to "true"

Disclaimer: I want to thank Tekkub for his fantastic addon: picoFPS for inspiration and some code ideas, kudos!

LUA config options:
MEMTHRESH: number (in kb) that is the minimum memory usage of displayed addons (indirect limit to number of addons shown). In other words, if an addon doesn't use more than the MEMTHRESH it will not be shown in the tooltip. Default set to 1 kb. Increase to improve performance.

UPDATEPERIOD: number that dictates how often the addon will refresh the calculations and function calls. Default set to 2 seconds. Increase to improve performance.

wantOnClick: boolean that controls the ability of turning auto-updating ON or OFF. Auto-updating allows for the tooltip to update continuously (based on set UPDATEPERIOD variable). Default set to "false". NOTE: some users will experience a slight decrease in performance if this option is set to "TRUE".
