Restart functionality for ForceConstantModel
Description
I think we should provide read/write functionality for FCM.
This would allow for the old FCM object in a SC to be saved which would save a lot of time since repopulating the FCM often takes longer than computing the fit_matrix.
Tasks
-
Implement restart functionality for FCM -
Add unittest for this new functionality -
Make StructureContainer save the FCM object to file via this new functionality.
