DynamicObjectRegistrationAction

If an object required for a simulation is present in a pre-compiled library that is not already linked to the application used, it may be dynamically linked using the following syntax, handled by DynamicObjectRegistrationAction,

[Problem]
  register_objects_from = 'PhaseFieldApp'
  library_path = '../../../../../phase_field/lib'
[]
