Examples (WIP)

Below are my ideas for the interface.

sdp::CelesTrakEOP eop_parser("data.csv");

eop_parser.load();  // all
eop_parser.load_range(5000, 5500);  // input mjd -> input mjd
eop_parser.load_range("2020-01-01", "2021-01-01");  // input date -> input date

eop_parser.load_from_begin(5500);  // table begin -> input end mjd
eop_parser.load_from_begin("2021-01-01");  // table begin -> input end date

eop_parser.load_to_end(5000);  // input begin mjd -> end
eop_parser.load_to_end("2020-01-01");  // input begin date -> end

sdp::celestrak_eop_t eop = parser.get_all(5612.6);  // all via struct?
double x = parser.get_dpsi(5612.6);  // one via method?
double x = parser.get(5612.6, sdp::eop::dPsi);  // one via enum?
