An interface for dealing with oceanographic cruises data
Create a Station,
julia> using OceanographyCruises
julia> st = Station(name="ALOHA", lat=22.75, lon=-158)
Station ALOHA (22.8N, 158.0W)a CruiseTrack of stations,
julia> N = 10 ;
julia> stations = [Station(name=string(i), lat=i, lon=2i) for i in 1:N] ;
julia> ct = CruiseTrack(stations=stations, name="TestCruiseTrack")
