* fix crash because of incomplete inheritance of BlendPoint and BlendCurve -> do not inherit from BaseClass
as consequebce make destructor non-virtual and remove getPyObject
* pass std::vector by const reference
* remove unneeded includes
* use more suitable Python exception types
* when returning with null from Python handler then set an exception
* harmonize file guards
* several optimizations or simplifications
* use modern C++
* harmonize command name
* fix copyright note
- the Flux solver must be executed before Heat and Electrostatic
- the analysis can have multiple Flux equations -> write a unique solver name to case.sif
- the Flux equation can currently only take 2 possible values. Therefore provide them as enum
- as the name implies, it must be possible to set the heat to different bodies
- for this a selection dialog is necessary
- check that heat is not zero
