5997	Improve CVODE in C-runtime to production-grade	Andreas Heuermann	Andreas Heuermann	"CVODE is implemented in the nightly builds and running.
See test overview at https://libraries.openmodelica.org/branches/cvode/Modelica_3.2.3/Modelica_3.2.3.html.

When comparing with the default DASSL solver there are still some failing or unvverfied tests and the solver needs way way more steps.

In addition most of the basic features DASSL and IDA offer are not implemented yet:
  - Non-Colored/Colored Numeric/Symbolic Jacobians
  - Sparse linear solver (KLU)
  - Improved error handling when failing to integrate
  - Additional user flags for most of the CVODE settings we use


For 1.16 we should at least make sure that the implementation is error free and the results are correct."	enhancement	new	critical	2.0.0	Run-time	v1.16.0-dev		CVODE, C-Runtime
