Include parameter to compute and store lat/lon/alt at each gate

[nguy]

I'd find it useful to have an optional function something like the pyart package provides that could compute lon-lat(-alt) for each gate and save into the file as additional variables.

Nick - would this be in Radx2Grid? Or do you want it in a radial file? Mike

A radial file would be preferable for my purposes.
