/**
* A Swing component that displays annotations in a text pane with highlighting. There is also a
* tree view for display details of annotations on which the user clicks. This class extends
* {@link JPanel} and so can be reused within any Swing application.
*
* To launch the viewer, call the {@link #setCAS(CAS)} method with the CAS to be viewed.
*
* The viewer is configurable via the following methods:
*
* - {@link #setConsistentColors(boolean)} - if set to true (default), the color assigned to any
* annotation type will be the same across all documents. If set to false, colors may vary across
* documents.
* - {@link #setDisplayedTypes(String[])} - specifies a set of types that will be highlighted in
* the viewer's text pane.
* - {@link #setHiddenTypes(String[])} - specifies a set of types that will NOT be highlighted in
* the viewer's text pane.
* - {@link #setHiddenFeatures(String[])} - specifies a set of features that will never shown in
* the viewer's annotation details tree.
* - {@link #setHighFrequencyTypes(String[])} - this can be used to specify a set of types that
* occur frequently. These types will the be assigned the most distinguishable colors.
* - {@link #setInitiallySelectedTypes(String[])} - this can be used to specify a set of types
* that will initially be selected (i.e. have their checkboxes checked) in the viewer. The default
* is for all types to be initially selected.
* - {@link #setRightToLeftTextOrientation(boolean)} - switches the text pane from left-to-right
* (default) to right-to-left mode. This is needed to support languages such as Arabic and Hebrew,
* which are read from right to left.
