Detailed Description

Author

Kurt Kramer

Describes the different fields of a dataset. There will be one instance of this *
class for each type of Dataset that you have in an application.  From this      *
object you can get information such as number of attributes, Attribute types,   *
weather they are nominal, continuous.  If nominal what are the accepted         *
values.                                                                         *
                                                                                *
Never delete an instance of a FileDesc object.                                  *
                                                                                *
Only one FileDesc object can exist for any Dataset.  Example the Forest Cover   *
dataset.  You can split the data into many files and manage them separately but *
you will only have one instance of a FileDesc object that they will all refer   *
to.  See "GetExistingFileDesc" method below.  You would initially create an     *
instance of FileDesc and then use "GetExistingFileDesc" to make sure that it is *
unique. This typically happens in the FeatureFileIO derived classes.            *
                                                                                *
