/**
 * The CommandInfo class is used by CommandMap implementations to
 * describe the results of command requests. It provides the requestor
 * with both the verb requested, as well as an instance of the
 * bean. There is also a method that will return the name of the
 * class that implements the command but <i>it is not guaranteed to
 * return a valid value</i>. The reason for this is to allow CommandMap
 * implmentations that subclass CommandInfo to provide special
 * behavior. For example a CommandMap could dynamically generate
 * JavaBeans. In this case, it might not be possible to create an
 * object with all the correct state information solely from the class
 * name.
