Added an integrator structure that can be configured at runtime
- Added Config structure for the integrator file.
- Added Integrator class.
- Compare characteristics against analytical functions in the unit test.
- Catch nan values in the initialization.
- Move
enum class
to pureenum
which is easier to handle with other datastructures using integers. - Add analytical backtracers for simple examples
@poem I can only add a single reviewer but your opinion on the integrator is welcomed
