Generalize software for multiple devices

[gadamc]

It's pretty clear that this software could be repurposed for any device that moves an object in 3 dimensions using analog input and output channels on NIDAQ. (In fact, it doesn't even need to be spatial dimensions!).

It would not be too much work to clone this repository, rename it to something more general, then layer on specifics.
In fact, the only thing that is really needed to is properly scale the analog voltage to the dimension of interest. (In the case of the Jena controller, this scaling is 8 microns per volt)

The very small downside of renaming is that there'd be a few side effects

• would need to migrate qt3utils to new package name in future versions. This would be somewhat trivial, and would likely dovetail with a need to define a 3d stage controller interface in qt3utils.
• would need to push new package to pypi - also trivial.
