I could be misunderstanding something fundamental about Boost::Units.  
Is it possible to declare a class field or method parameter with a  
type that indicates it represents a velocity without specifying  
whether the value is in meters per second or miles per hour?

I'd like to allow any kind of velocity to be specified and perform  
operations independent of the units being used. For example, if I set  
the velocity of some object to 60 miles per hour and then call a  
method to determine how far it will travel in 2 hours, I'd like to get  
back 120 miles. I'd also like to be able to set the velocity to 10  
meters per second, ask the same question, and get back 72000 meters.
