Spark Max - LabView velocity sample -- suggested update

[jsimpso81]

Based on a question from someone on Chief Delphi, I took a quick look at the Spark Max velocity control example. I noticed that it used VI that didn't appear in the palette. I made some changes to the sample to use the palette routines. I also moved the main user interface to Robot Main to make it easier to run. Do what you want this this. We have never used the Spark Max so I couldn't test this.... The pull with changes is #20
