* This is a utility class to centralize all action that should be performed
* in a <tt>doPrivileged()</tt> block. To perform a secure action, simply
* create an instance of this class and use the specific method to perform
* the desired action. When an instance is created, this class will capture
* the security context and will then use that context when checking for
* permission to perform the action. Instances of this class should not be
* passed around since they may grant the receiver a capability to perform
* privileged actions.
