Provides a Swing component for viewing an {@link com.redhat.rhdb.explain.Explain
Explain} object. The main class in this package is {@link
com.redhat.rhdb.explain.view.ExplainView}. It uses a {@link
com.redhat.rhdb.treedisplay.TreeDisplay} component for displaying the plan tree
of the Explain object that it is viewing and provides several wrapper methods
that manipulate how plan trees are displayed.
The {@link com.redhat.rhdb.explain.view.ExplainViewListener} interface should be
implemented by any class that needs to listen for events generated by the
ExplainView component.
