+/**
+ ** SimpleBeanInfo is a class you may extend to more easily
+ ** provide select information to the Introspector. It
+ ** implements all of the methods in BeanInfo by returning
+ ** null and forces the Introspector to behave exactly as
+ ** if there were no BeanInfo class at all (Introspecting
+ ** everything).<P>
+ **
+ ** Overriding one or two of these functions
+ ** to give explicit information on only those things you
+ ** wish to give explicit information is perfectly safe,
+ ** and even desirable.<P>
+ **
+ ** See the BeanInfo class for information on what the
+ ** various methods actually do.
