Creating submodels and directivity models

Two types of source models can automatically be created from a free field simulations:

• Use .create_boundary_velocity_submodel() to create a boundary velocity submodel source, see Boundary Velocity Submodels.
• Use .create_source_directivity() to create Directive source, see Directional Sources

Both these functions will create a source in the organizations libraries (tsdk.boundary_velocity_submodel_library or tsdk.source_directivity_library), which is makes them available for everyone in the organization to use as sources in other simulations.
