Vector2Property to get units?

[zepumph]

For PhET-iO, it was requested that some Vector2 Properties could get units. I think it would be awesome to add this. @samreid what do you think? I was just going to use units.js and copy the same sort of pattern as NumberProperty. Then add that to studio.

See phetsims/projectile-motion#219 for the requests for places like:

Units to:
projectileMotion.introScreen.model.measuringTape.basePositionProperty: m
projectileMotion.introScreen.model.measuringTape.tipPositionProperty: m
projectileMotion.introScreen.model.tracer.positionProperty: m

Units are already implemented in Property, not in NumberProperty, so it is possible Vector2Property already has support for units.

Oh I see. Let me see better. BTW this would be best to link phetsims/projectile-motion#244 to.

Seems like it! Thanks for the reminder. Sorry to bother.
