040     * <p>
041     * IndexShapeFile is an application that can be used to index an ESRI ShapeFiles(tm). It indexes
042     * both the geometry and the alphanumeric attributes
043     * </p>
044     *
045     * <p>
046     * The application shows a file chooser with which the user can select a file. When a file is
047     * choosen the application opens it and shows the attributes. The user can now select the attributes
048     * that has to be indexed. Already indexed attributes are already selected and can be deselected.
049     * For alphanumeric attributes the user can indicate if the attribute is unique or not.
050     * </p>
051     *
052     * <p>
053     * After selecting the attributes the application creates the needed indexes and loops over all the
054     * features in the shape file. For every feature the application inserts the attributes in the right
055     * index. After looping over the features the application closes the shapefile and the created
056     * indexes and removes the indexes that are no longer needed (eg. the index for the attributes that
057     * are deselected).
058     * </p>
059     *
060     * <p>
061     * It is not possible to transform a unique index to a non-unique index or back.
062     * </p>
