        These are convenience functions that do most of the work of navigating through
        the resolutions information nested under each reference model. The resolutions 
        info is never displayed in the UI, but you can think of its structure like so:
                ReferenceModel (model)
                        - Resolutions (special container)
                                - res0 (compound parameter)
                                        - File parameter (eg., "<installationpath>/Data/XSI_SAMPLES/Models/ManSkeleton_Basic.emdl")
                                        - Name parameter (eg., "MyRes")
                                + res1
                                  ...
                                + resN
        In order to access this info you need to use the SIObject.NestedObjects property
        on the ReferenceModel, the Resolutions container, and then each resolution parameter.
