  CLASS: ICBTableEA     --DVM
  PUBLIC METHODS:
    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.
    icbTbl()       - returns a pointer to the C-array of longADs.
    numEnts()      - returns the number of ADs in the ICBTable
    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.
    operator!=()   - Returns False if all fields are the same;
                   otherwise return True.
    verifyISO()    - Returns a non-zero error if the ISO image at the
                   supplied byte pointer location does not match the
                   current state of the object.
