public PluginDescription getPluginDescription(String className) {

This class maintains a collection of all plugin classes that are acceptable for a given tool
type.  Simple applications with only one plugin type can use the
{@link DefaultPluginsConfiguration}.  More complex tools can support a subset of the available
plugins. Those tools should create custom subclasses for each tool type, that filter out plugins
that are not appropriate for that tool type.
