- adjusted molar air gas constant

Adding directivity manager reverse getter function to export IDs from a prop anchor with a directivity pointer

Changing default encode W option to false, will now per default export oly XYZ componets of VistaVector to JSON format

- now use double vectors instead of float vectors
- now return interpolated values from spline polynomials instead of default values

- added functions for en-/decoding of double vectors

- added checks to Decode functions to check whether expected JSON nodes exist
- otherwise throw ITAException

- now allows default constructor for CImport classes using dummy values
- JSON create functions now use this default constructors

- now uses new ITABase splines and piecewise polynomials
- adaption according to namespace changes of ITABase classes

- reformat

- added falsely removed operator= again
- added JSON de-/encode functions for import profiles
- extended tests accordingly

- added (de)coding functions for std::vector<float>

- added prototype versions of profiles for imported data
- cleanup
   - operator= is now auto generated
   - properly ended inline methods with ;
   - moved some code to cpp files

- moved Vista functions to a single but renamed header file
- fixed an inline bug

- now parses spreading loss of CSensorInhomogeneous in dB

- removed some "inline" and added ";" after some inline functions

- now uses shared_ptr instead of unique_ptr
- has access functions to weather profiles
- no friend functions necessary anymore

Atmosphere - JSON Encode WeatherProfiles
- now properly creates and returns shared_ptr

- added some reserve() calls for performance improvements

- now parses spreading loss of CSensorInhomogeneous in dB
