/**
* Simple facade to XStream library, a Java-XML serialization tool.
* <p>
* <hr>
* <b>Example</b><blockquote>
*
* <pre>
* XStream xstream = new XStream();
* String xml = xstream.toXML(myObject); // serialize to XML
* Object myObject2 = xstream.fromXML(xml); // deserialize from XML
* </pre>
*
* </blockquote>
* <hr>
*
* <h3>Aliasing classes</h3>
*
* <p>
* To create shorter XML, you can specify aliases for classes using the <code>alias()</code>
* method. For example, you can shorten all occurrences of element
* <code><com.blah.MyThing></code> to <code><my-thing></code> by registering an
* alias for the class.
* <p>
* <hr>
* <blockquote>
*
* <pre>
* xstream.alias("my-thing", MyThing.class);
* </pre>
*
* </blockquote>
* <hr>
*
* <h3>Converters</h3>
*
* <p>
* XStream contains a map of {@link com.thoughtworks.xstream.converters.Converter} instances, each
* of which acts as a strategy for converting a particular type of class to XML and back again. Out
* of the box, XStream contains converters for most basic types (String, Date, int, boolean, etc)
* and collections (Map, List, Set, Properties, etc). For other objects reflection is used to
* serialize each field recursively.
* </p>
*
* <p>
* Extra converters can be registered using the <code>registerConverter()</code> method. Some
* non-standard converters are supplied in the {@link com.thoughtworks.xstream.converters.extended}
* package and you can create your own by implementing the
* {@link com.thoughtworks.xstream.converters.Converter} interface.
* </p>
*
* <p>
* <hr>
* <b>Example</b><blockquote>
*
* <pre>
* xstream.registerConverter(new SqlTimestampConverter());
* xstream.registerConverter(new DynamicProxyConverter());
* </pre>
*
* </blockquote>
* <hr>
* <p>
* The converters can be registered with an explicit priority. By default they are registered with
* XStream.PRIORITY_NORMAL. Converters of same priority will be used in the reverse sequence
* they have been registered. The default converter, i.e. the converter which will be used if
* no other registered converter is suitable, can be registered with priority
* XStream.PRIORITY_VERY_LOW. XStream uses by default the
* {@link com.thoughtworks.xstream.converters.reflection.ReflectionConverter} as the fallback
* converter.
* </p>
*
* <p>
* <hr>
* <b>Example</b><blockquote>
*
* <pre>
* xstream.registerConverter(new CustomDefaultConverter(), XStream.PRIORITY_VERY_LOW);
* </pre>
*
* </blockquote>
* <hr>
*
* <h3>Object graphs</h3>
*
* <p>
* XStream has support for object graphs; a deserialized object graph will keep references intact,
* including circular references.
* </p>
*
* <p>
* XStream can signify references in XML using either relative/absolute XPath or IDs. The mode can be changed using
* <code>setMode()</code>:
* </p>
*
* <table border='1'>
* <caption></caption>
* <tr>
* <td><code>xstream.setMode(XStream.XPATH_RELATIVE_REFERENCES);</code></td>
* <td><i>(Default)</i> Uses XPath relative references to signify duplicate references. This produces XML
* with the least clutter.</td>
* </tr>
* <tr>
* <td><code>xstream.setMode(XStream.XPATH_ABSOLUTE_REFERENCES);</code></td>
* <td>Uses XPath absolute references to signify duplicate
* references. This produces XML with the least clutter.</td>
* </tr>
* <tr>
* <td><code>xstream.setMode(XStream.SINGLE_NODE_XPATH_RELATIVE_REFERENCES);</code></td>
* <td>Uses XPath relative references to signify duplicate references. The XPath expression ensures that
* a single node only is selected always.</td>
* </tr>
* <tr>
* <td><code>xstream.setMode(XStream.SINGLE_NODE_XPATH_ABSOLUTE_REFERENCES);</code></td>
* <td>Uses XPath absolute references to signify duplicate references. The XPath expression ensures that
* a single node only is selected always.</td>
* </tr>
* <tr>
* <td><code>xstream.setMode(XStream.ID_REFERENCES);</code></td>
* <td>Uses ID references to signify duplicate references. In some scenarios, such as when using
* hand-written XML, this is easier to work with.</td>
* </tr>
* <tr>
* <td><code>xstream.setMode(XStream.NO_REFERENCES);</code></td>
* <td>This disables object graph support and treats the object structure like a tree. Duplicate
* references are treated as two separate objects and circular references cause an exception. This
* is slightly faster and uses less memory than the other two modes.</td>
* </tr>
* </table>
* <h3>Thread safety</h3>
* <p>
* The XStream instance is thread-safe. That is, once the XStream instance has been created and
* configured, it may be shared across multiple threads allowing objects to be
* serialized/deserialized concurrently. <em>Note, that this only applies if annotations are not
* auto-detected on-the-fly.</em>
* </p>
* <h3>Implicit collections</h3>
*
* <p>
* To avoid the need for special tags for collections, you can define implicit collections using one
* of the <code>addImplicitCollection</code> methods.
* </p>
