Kinks in profiles

[MarAlder]

@rainman110 has added a TiGL feature which accounts for kinks in profiles. The proposal #629 is merged to develop (see 3694d8f). Please have a look at the new kinks and parameterMap elements in the curvePointListXYZType:

• Schema diagram
• Documentation

Let us know if you have any comments so that I can plan the implementation of the schema modification in the next CPACS release.

Would it make sense to extend the definition of kinks in profiles #629 to guide curves as well?
The rXDirection element could similarly be extended with kinks and parameterMap elements. The implementation in TiGL DLR-SC/tigl#659 would be probably (hopefully) not that different.

@ProgramAlarm1202 It is already possible to have a kink in the guide curve AT a section. I would avoid defining additional kinks within a segment though.

[ProgramAlarm1202]

@rainman110 Good point. A limitation is that a section is always planar. But I suppose if you want a kink at a particular location, you can always insert an additional section.

@rainman110 @joergbrech : At the stakeholder meeting the question was raised whether we use 0 or 1 indexing for the [kinks](https://www.cpacs.de/documentation/CPACS_development/html/d0271c9a-2b38-36af-5f3f-50d49dabdbda.htm) vector (because XPATH starts with index 1 and I think many TiGL functions do so as well, right?). What do you think?

[MarAlder]

We have decided to use 1 indexing throughout CPACS (i.e., counting indices of vectors from 1). To distinguish the CPACS 3.3 schema from the TiGL 3.1 implementation (using 0 indexing) I renamed the corresponding parameters:
