/**

* The core class of gir2java. Responsible for traversing the XOM tree of GIR XML documents, and building a

* CodeModel AST from them. There is one GirCodebase for all GIR XMLs you want to generate a common Java

* codebase for. The general correct usage is something like

*

* <pre><code>

* Document doc = getGirFromSomewhere();

* GirCodebase cb = new GirCodebase();

* cb.addGir(doc);

* cb.addGir(someOtherDoc);

* cb.saveJava(javadir);

* </code></pre>
