This function sets up the callback function and private data to be used by the value model when
retrieving data from the model via ITypedValueModel_GetValue(). Models that store arbitrarily complex
data may use a callback (defined by PFNTADAPTGET) to retrieve specific portions of the model's
data. For example, a value model that stores information to be displayed in a list -- say, an
icon, some text, plus some indication of the text style -- could specify an adaptive get
callback routine that could return just the text, or just the icon -- apart from the entire data

need access to specialized information not normally available when accessing the data
stored in the model. This pointer is passed to the model's PFNTADAPTGET function when
the model has been asked to retrieve the data.
