Smart Variable Watcher

This is a smarter variable watcher that replaces the standard built-in version. This version uses less CPU for large projects.

When large arrays are defined, it may take a long time for the grid to render the data. However, once rendered, the data will update much faster than the ARC built-in variable watcher. 

Please provide error feedback as this hasn't been thoroughly tested. If you receive errors, let me know in the comment box below.

*Note: It is not recommended to run a production project with this robot skill.

- cache updates to a nonblocking list and update the grid in an interval
- allow specifying what variables to watch (or maybe just an option to ignore arrays)

I'm curious, I use many variables in my large project. I have several scripts that pause and wait for some of these variable change before restarting. Will using the Smart Variable Watcher effect this function?
Dave - any of the variable watchers are for debugging. If you're debugging and need a variable watcher, use the smart variable watcher. There's no need to add any variable watchers if you don't need them. But if you do need one, use the smart variable watcher instead.
Dave - also i should add that I left the original variable watcher in ARC for legacy purposes. It can still be used for small projects.
Thanks DJ! Good to know. I'm trying to stay up to speed with all the changes but sometimes I get behind. 

I do have a variable watcher in my project. I didn't know it was eating up so much CPU. It's seems I was always adding to and debugging so I never removed it. Didn't think it was a problem and I had a lot of things going on. Thanks for the streamlined VW. 

I've been spending most of my robot time this past couple years building robots and installing hardware because of a couple large B9 Robot rebuilds I'm doing. It's been a slow road. I've just been using basic ARC projects to test different section and functions of the robots. I'll soon (re)start the software/programming process on a grand scale. I'm really excited about all the new things ARC can do compared to just 3 years ago. Can't wait to get them into my robot.
