Set a Multipart Part Body from BinData

Demonstrates Rest.SetMultipartBodyBd, which sets the binary body of the selected multipart part from a BinData.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background. A multipart request is assembled part by part: the part selector chooses the part being built, header fields describe it, and a SetMultipartBody method supplies its content. The request is then sent with a multipart send or full-request method.
