Version 1.0.0

- Added CoordSys.taiFromDate methods.
- Added besslianEpochFromTAI and taiFromBesselianEpoch functions.
- AppGeoCoordSys changed maxAge from 1 second to 0.05 seconds. This will make lunar tracking errors
  negligible even at a high update rate.
- Added functions appTopoFromAppGeo, appGeoFromAppTopo, obsFromAppTopo and appTopoFromObs,
  and removed similar methods from AppTopoCoordSys and ObsCoordSys.
- Enhanced the documentation, including a working example and links to most classes
  and functions from the main source code documenation page, with working links.
