/**
 * 
 * This class is intended to be used from an MWE workflow.
 * 
 * It instantiates and registers the Ecore support for Xtext, which allows for
 * referencing ecore models from any Xtext language.
 * 
 * Usage:
 * 
 * <pre>
 *    component = org.eclipse.xtext.ecore.EcoreSupport{}
 * </pre>
 * 
 * If you want to provide a different guice guiceModule than the default one (
 * {@link BPMnRuntimeModule}) in order to change any implementation classes, you
 * can make use of the property guiceModule. E.g. :
 * 
 * <pre>
 *    component = org.eclipse.xtext.ecore.EcoreSupport{
 *       guiceModule = my.special.CustomizedEcoreRuntimeModule {}
 *    }
 * </pre>
