[time-nuts] nuts about position

I haven't done any extensive testing of how accurate the results are, but comparing them to the position produced by a L1/L2 (error ellipses < 50mm) they seem to be correct.  

One issue to be aware of is that some receivers want altitude in othometric height (MSL) and others use geoid (GPS) height.   If you are transferring the PPP results to a receiver you need to watch out for what the receiver wants.   Also MSL based receivers may be using different orthometric models, so knowing how to convert GPS height to what the receiver uses can be problematic.
