/**
 * This is the exportation class relying on the API (= on the full hierarchy of
 * metaclasses stored in the model). Note that another way to export a model would
 * be to use ExporterXSL, which is based on an XSL transformation of XMI. 
 * A class implementing ExporterAPI must reside in a subfolder containing a class
 * named PHP_UML_<name of the output format>_Exporter. This class must also have a
 * public method "generate", which is used to start the serialization process.
