Coordinate/unit transformations
We will need to do various coordinate/unit transformations, these are in lal
and we can use it for now, but most of them will be achievable using standard python packages.
@sylvia.biscoveanu you've already played with some conversions, would you be willing to be the point person on this? Keep track of what is needed and have some sort of sane cataloguing/storage system.
One thing we'll want is to be able to convert between human time, sidereal time and gps time.
This is a good reference http://docs.astropy.org/en/stable/time/
We'll then want physical constants/conversion to bounce between different unit systems. (Personally, I'd vote against getting tied into astropy.units
for everything.)
