   * A on object representing an array of CAS elements.
   * An element can be either a FeatureStructure or a float or an int or a
   * string. For each such element type there is a sub-class of BasicListFS
   * implementing this template interface with type specific methods:
   * ArrayFS, IntArrayFS, FloatArrayFS, StringArrayFS.
   *
   * All get methods may throw an <code>InvalidFSObjectException</code> if the
   * feature structure object is not valid.
   * All access methods using array indexes may throw an
   * <code>FSArrayOutOfBoundsException</code> if the index is >= the array size.
   *
   * Creating an array can be done like this:
     @code
     // store elements of a vector of strings in an array feature
     FeatureStructure fsNewString;           // re-used for each new string
     const size_t uiARRAY_SIZE = vecStrings.size();
     StringArrayFS fsNewArray = tcas.createStringArrayFS(uiARRAY_SIZE); // create an array
     // build up a fs array from our vector
     for (size_t i = 0; i < vecStrings.size(); ++i) {
        fsNewArray.set(i, vecStrings[i]);
     }
     // now that the array is complete, set the feature value to the array
     fsWithArrayFeature.setFSValue(fArrayFeature, fsNewArray);
     @endcode
   * Accessing a array can be done like this:
     @code
     // get array
     StringArrayFS fsArray = fsWithArrayFeature.getStringArrayFSValue(fArrayFeature);
     // iterate array
     for (size_t i = 0; i < fsArray.size(); ++i) {
        cout << fsArray.get(i) << " ";
     }
     @endcode
   *
   * The example uses StringArrayFS to show the usage of the interfaces with
   * strings. Usage of FeatureStructure, int or float values is analogous.
   *
   * Arrays can not be resized after creation. If more (or less) elements are
   * required in the array a new array must be created.
   * Elements from the old array may be copied to then new array.
   * Finally the new array must be assigned to the array feature holding the
   * old array.

   * @see IntArrayFS
