*
* @param container container to which items should be inserted
*
* @retval MFD_SUCCESS : success.
* @retval MFD_RESOURCE_UNAVAILABLE : Can't access data source
* @retval MFD_ERROR : other error.
*
* This function is called to load the index(es) (and data, optionally)
* for the every row in the data set.
*
* @remark
* While loading the data, the only important thing is the indexes.
* If access to your data is cheap/fast (e.g. you have a pointer to a
* structure in memory), it would make sense to update the data here.
* If, however, the accessing the data invovles more work (e.g. parsing
* some other existing data, or peforming calculations to derive the data),
* then you can limit yourself to setting the indexes and saving any
* information you will need later. Then use the saved information in
* nvCtrlTable_row_prep() for populating data.
*
* @note
* If you need consistency between rows (like you want statistics
* for each row to be from the same time frame), you should set all
* data here.
