Task 22 - Done!

…to write a Java program called AttributeConverter that takes as input
an input XML file and uses JAXP 1.3’s SAX API to convert all attributes
to child elements and serialize the result to System.out.6
For instance, given
    <foo><bar baz="qux" quux="quuux"/></foo>
as input, your program should produce
    <?xml version="1.0" encoding="UTF-8"?>
    <foo><bar><baz>qux</baz><quux>quuux</quux></bar></foo>
