In-memory data exchange

Description
  • ugiocb.cs: Exchanging data between model and host application. Callbacks for exchanging data: sparse data, string indices (requires burglar13.mos)
  • ugiodense.cs: Exchanging data between model and host application. Dense data (requires burglar8d.mos)
  • ugioscalar.cs: Exchanging data between model and host application. Scalars (requires burglar11.mos)
  • ugiosparse.cs: Exchanging data between model and host application. Sparse data, string indices (requires burglar9d.mos)
  • ugdatastream.cs: Exchanging data between model and host application using a DataStream. Sparse data, string indices (requires burglar13.mos)
