Write GPX files #3

Closed chetbox closed 6 years ago

chetbox commented 6 years ago

Write GPX files to an OutputStream by supplying the appropriate Observable<Point> streams.

Example:

GpxWriter(
  creator: "GpxKit",
  track: Observable.just(Observable.from([
    Point(lat: 54.9328621088893, lon: 9.860624216140083, elevation: 0, time: Date(timeIntervalSince1970: 1505900660)),
    Point(lat: 54.93293237320851, lon: 9.86092208681491, elevation: 1.1, time: Date(timeIntervalSince1970: 1505900661)),
    Point(lat: 54.93327743521187, lon: 9.86187816543752, elevation: 2.22, time: Date(timeIntervalSince1970: 1505900662)),
    Point(lat: 54.93342326167919, lon: 9.86243984967986, elevation: 3.333, time: Date(timeIntervalSince1970: 1505900663))
  ]))
)
.write(to: outputStream)
.subscribe()

generates:

Note that GpxKitTests has been renamed to GpxParserTests. There's a new GpxWriterTests with all the new tests.
