         The Orekit library relies on some external data for physical models. 
         Typical data are the Earth Orientation Parameters and the leap seconds history, 
         both being provided by the IERS or the planetary ephemerides provided by JPL. 
         Such data is stored in text or binary files with specific formats that Orekit knows 
         how to read, and needs to be provided for the library to work.
