Create reference frame class

[osrf-migration]

It would strengthen our API if a vector class could have a reference frame associated with it. Currently, we have the reference frames listed in function names (GetWorldLinearVel for example). It could also be relevant for matrices; the inertia matrix can be expressed in a body-fixed frame or world frame for example.

See this dartsim pull request for an example implementation.
