| A viewer sorter is used by a
StructuredViewer to reorder the elements
provided by its content provider.
The default compare method compares elements using two steps.
The first step uses the values returned from category.
By default, all elements are in the same category.
The second level is based on a case insensitive compare of the strings obtained
from the content viewer's label provider via ILabelProvider.getText.
Subclasses may implement the isSorterProperty method;
they may reimplement the category method to provide
categorization; and they may override the compare methods
to provide a totally different way of sorting elements.
It is recommended to use ViewerComparator instead.
