/**
 * Implementation of {@link InitialContextFactory} that allows lookup of transaction manager
 * and registered resources.
 * <p>
 * The easiest way to use this provider is to create a <code>jndi.properties</code> file
 * in your classpath with this content:
 * <pre>java.naming.factory.initial=bitronix.tm.jndi.BitronixInitialContextFactory</pre>
 * Alternatively, you can create a {@link javax.naming.InitialContext} object with an environment
 * pointing to this class:
 * <pre>
 * Hashtable env = new Hashtable();
 * env.put(Context.INITIAL_CONTEXT_FACTORY, "bitronix.tm.jndi.BitronixInitialContextFactory");
 * Context ctx = new InitialContext(env);
 * </pre>
 * </p>
 * <p>The transaction manager can be looked up at the standard URL <code>java:comp/UserTransaction</code>
 * while resources can be looked up using their unique name as set in 
 * {@link bitronix.tm.resource.common.ResourceBean#getUniqueName()}.
 * </p>
