CANTalon: No resource counting to disallow overallocation about allwpilib

[PeterMitrano]

sounds super helpful. Do teams struggle with this often? It seems like a stupid error that might be hard to find.

[ThadHouse]

All of the other classes throw exceptions, so this is the odd class out. And also yes its pretty common especially early in the season. I'll wait until after my HAL proposal to do this, as this can be implemented either at the HAL level or the WPILib level.

From a design perspective I think it makes more sense to turn the CANTalon constructor private and create a "factory" static method that initializes singletons for each CAN ID you call it with. (and extend this to the other classes that need a similar pattern)

[PeterJohnson]

While singletons might have been a cleaner design at inception, making such a change now would break thousands of existing programs. Per https://github.com/wpilibsuite/allwpilib/blob/master/CONTRIBUTING.md#what-to-contribute, "backwards compatibility is very important for WPILib".
