Create option for inertia... about virtual_robot

[jkenney2]

Yes,

It is essentially a "math-based" rather than a "physics-based" simulator. Changes in motor speed occur instantaneously, and there is no skidding of the wheels. Motor behavior is the same regardless of whether in RUN_USING_ENCODER or RUN_WITHOUT_ENCODER mode.

It would be pretty easy to modify the DcMotorImpl class to simulate some inertia, and add a slider in the UI to control it. I'll look at that.

I'm not sure how much it would improve the difference between simulator and real robot, as it wouldn't account for differing loads on the different wheels, and the effect of skidding. But, it would be interesting to try.

Just created a new branch, "inertia", and implemented the suggested change in it. I think it works as expected; give it a try. Not yet merged into the master branch.

Merged "inertia" branch into master.
