Doesn't handle breakpoints already specified in em.

Hey, I see there's a toEm method that's assuming any value passed in is going to be pixels. There should be a check to see if the values are already ems.

@mikestopcontinues, thanks for the feedback. Great point. I will add validation, which would warn that all transmitted values should be in pixels.
