/**
 * This class is for various network permissions.
 * A NetPermission contains a name (also referred to as a "target name") but
 * no actions list; you either have the named permission
 * or you don't.
 * <P>
 * The target name is the name of the network permission (see below). The naming
 * convention follows the  hierarchical property naming convention.
 * Also, an asterisk
 * may appear at the end of the name, following a ".", or by itself, to
 * signify a wildcard match. For example: "foo.*" or "*" is valid,
 * "*foo" or "a*b" is not valid.
 * <P>
 * The following table lists all the possible NetPermission target names,
 * and for each provides a description of what the permission allows
 * and a discussion of the risks of granting code the permission.
 * <P>
 *
 * <table border=1 cellpadding=5>
 * <tr>
 * <th>Permission Target Name</th>
 * <th>What the Permission Allows</th>
 * <th>Risks of Allowing this Permission</th>

 *
 * <tr>
 *   <td>setDefaultAuthenticator</td>
 *   <td>The ability to set the
 * way authentication information is retrieved when
 * a proxy or HTTP server asks for authentication</td>
 *   <td>Malicious
 * code can set an authenticator that monitors and steals user
 * authentication input as it retrieves the input from the user.</td>

 *   <td>specifyStreamHandler</td>
 *   <td>The ability
 * to specify a stream handler when constructing a URL</td>
 *   <td>Malicious code may create a URL with resources that it would
normally not have access to (like file:/foo/fum/), specifying a
stream handler that gets the actual bytes from someplace it does 
have access to. Thus it might be able to trick the system into
creating a ProtectionDomain/CodeSource for a class even though
that class really didn't come from that location.</td>
