  CLASS: MacVolumeInfoEA     --DVM
  PUBLIC METHODS:
    lastModifyDate()    - Gets or sets appropriate field
    lastBackupDate()    - Gets or sets appropriate field
    volumeFinderInfo()  - Returns a reference to the Int32Table.
 
    error()        - Returns any state errors. Should be called after
                    construction and after any fromISO() or toISO() .
    attrType()     - Returns the value of the attrType field.
    attrSubtype()  - Returns the value of the attrSubtype field.
    attrID()       - Returns the String identifying the Attr.
    minAttrLen()   - Returns the minimum size the EA may be set to.
    attrLen()      - Gets or sets the EA to the supplied length. If
                   the new value is too short or disallowed for some
                   reason, it returns an error indicating that.
    clear()        - Sets the state to the exact same as right after 
                   construction. All fields are initialized to
                   defaults and/or zeroes.
    toISO()        - Translates the structure to its ISO representation
                   at the supplied byte pointer.
    fromISO()      - Translates the structure from its ISO
                   representation at the supplied byte pointer.
 
  USAGE NOTES:
   Note that dates are passed in and out of the fields via a time_t.
   Also note that the example below demonstrates how to access the
   volumeFinderInfo array members:
 
   for (int i=0; i<8; i++) {
       printf("vfi[%d]=%d\n",mviea.volumeFinderInfo()[i]);
   }
