Refactor: Encapsulation of state_elec_t attributes "modelmb data"
Part of refactoring of state_elec_t attributes.
This MR:
- Migrate modelmb source files to their own folder for better separation of features
- Encapsulates free-floating modelmb data into a Youngs diagram type
- Leaves the encapsulated instance of Youngs diagram type in
st
object, as propagating it as an argument up the call stack should be done as a separate MR, once one considers what argumentsscf_run
should have, for example. NOTE, this will be a recurring theme
