Function create_system 

pub fn create_system(
    tx: &mut Transaction,
    global_id: &str,
    name: Option<&str>,
) -> SystemAuthoringResult<EntityId>

Stage an IfcSystem.

Writes the IFC4/IFC4X3 layout with OwnerHistory $, so the record is IFC4/IFC4X3 only; use create_system_with_owner_history for a release-bound record, which IFC2X3 needs.

Errors

Refuses a malformed GlobalId.
