Dashboard Overload

[TheBassett]

This shouldn't be a problem under normal circumstances, but it's worth mentioning - smart dashboard may be being updated a lot.

If the "Show Inputs" class is running, then SDB is updating all values when the scheduler is calling its execute (probably comparable to time of "teleop periodic"). I forget the structure of SDB but I know it does record many values in it's network tables - if these values are updated too much w/o being cleared there may be a problem. I think SDB stores the values on the network as well.

Again, the data being transferred/stored is minuscule, however, if it is updated every 20ms during a match on a network with camera tracking there might start to be problems.

Thanks Alex -- good point, we should be careful on bandwidth usage. This
code is for a test chassis so regular updates here are probably not too bad!

Hey Alex
What are your thoughts on limiting the amount we update SmartDashboard
without compromising on accuracy? I have ideas of my own, but given that
you've pointed out the problem I imagine you have some experience or prior
notions about what should be done to fix it. Thanks for pointing it out!

PS: I know FRC code is cool, but you do have a life! As much as we love
your help and consideration, we don't want to burden you!

PPS: GitHub is awesome
