Log:
- Reaarangement of files under the examples/ directory.
- PatternLayout can now easily deal with new conversion words.
Added test cases in relation to this enhancement. More tests to follow.
- Changed MyPatternLayout under examples to take advantage of the
new PatternLayout architecture. Notice how easy it is to add a new
conversion word.

/**
A simple {@link NumberCruncher} implementation that logs its
progress when factoring numbers. The purpose of the whole exercise
is to show the use of nested diagnostic contexts in order to
distinguish the log output from different client requests.
<pre>
<b>Usage:</b> java org.apache.log4j.examples.NumberCruncherServer <em>configFile</em>
where <em>configFile</em> is a log4j configuration file.
</pre>
We supply a simple config file <a href=doc-files/factor.lcf>factor.lcf</a>
for directing log output to the file <code>factor.log</code>.
<p>Try it yourself by starting a <code>NumberCruncherServer</code>
and make queries from multiple {@link NumberCruncherClient
NumberCruncherClients} to factor numbers.
<p><b><a href="doc-files/factor.html">Sample output</a></b> shows the log
output when two clients connect to the server near simultaneously.
<p>See <a href=doc-files/NumberCruncherServer.java>source</a> code
of <code>NumberCruncherServer</code> for more details.
<p>Note that class files for the example code is not included in
any of the distributed log4j jar files. You will have to add the
directory <code>/dir-where-you-unpacked-log4j/classes</code> to
your classpath before trying out the examples.

<center><h2>Log4j output of two near-simultaneous requests</h2></center>
<p>Here is the logged output when two clients ask to factor two
integers near-simultanesouly. The client on the host 128.178.50.84
asks to factor the prime number 359. The client on the host 9.4.2.196
asks to factor the number 347 (also a prime).
<p>The NDC is placed between parantheses in bold. The NDC information
consists of the client's host and the number to factor. Since the two
requests have distinct NDCs, their output can be easily separated.
