<P>
This class describes the support needed to implement security.
 <p>
 Three main pieces of functionality are required to implement
 security for JavaScript. First, it must be possible to define
 classes with an associated security domain. (This security
 domain may be any object incorporating notion of access
 restrictions that has meaning to an embedding; for a client-side
 JavaScript embedding this would typically be
 java.security.ProtectionDomain or similar object depending on an
 origin URL and/or a digital certificate.)
 Next it must be possible to get a security domain object that
 allows a particular action only if all security domains
 associated with code on the current Java stack allows it. And
 finally, it must be possible to execute script code with
 associated security domain injected into Java stack.
 <p>
 These three pieces of functionality are encapsulated in the
 SecurityController class.
