Merge branch '8-create-application-examples' of https://collaborating.tuhh.de/m-8/hykops into 8-create-application-examples

added full support for spiral and tilt in both application examples on propellers and scaling of the entire propeller to the modification of a pff

batch scripts calling powershell scripts in the application examples for windows and some formatting

documentation and slimmed, improved implementation as well as translation to english of the application example on mofifying a propeller from a pff

documentation and slimmed, improved implementation as well as translation to english of the application example on creating a propeller from parameter distributions

improved documentation and implementation of the application example on exporting from a hykops geometry

Accept PFFs without version number and description when parsing PFFs. Ensure the curves for the suction and pressure sides for profiles in a PFF are parsed s.t. the geometry is consitent.

Improved cubic spline interpolation and slimmed interface for the extrapolation function in ISplines

Changes to the build system to link everything statically on windows and everything but boost statically on linux. Furthermore, Release is set as the default build type to reduce the size of the library.

Merge changes commited to 1-open-source-license into master

See merge request !6

Added compability for OpenSUSE 42.3 including cmake as low as 3.5.2 and fixed wording in license sections.

Resolve "Open source license"

Closes #7 and #1

See merge request !5

Closes #4 and #2

See merge request !4

The compilation and execution of libraries and binaries with shared and static libraries has succeeded on Windows 11, OpenSUSE 15.2 and Debian 11.

Closes #4

See merge request !3

Fixed order of additional options required for Windows and added an interface target to facilitate linking.

Adjusted further std::map::insert operations to comply with the logic from QMap, the code once was based on.

Erased std::map entries if a new one is to be inserted, because that is what QMap::insert does. Direct change to insert_or_assign is only possible staring from C++17.

Splitted implementation and defition of mapkeys, and ensure compilation of targets using HYKOPS with C++11 to 20.

Adjusted ranges for for-loops in lofttobsplinesurface to avoid segmenation faults caused by the original design while creating almost idential surfaces
