[x3d-public] x3d java sai. Don't know how to add IMPORT and EXPORT to objects - fixed

[Don Brutzman]

You are right, these objects are missing from allowed X3DChildrenNode typing required by addChildren methods.

	http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/java/Networking/EXPORTObject.html

	http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/java/Networking/IMPORTObject.html

There is a bit of an X3D Object Model issue here, how to make them compatible.  Distinctions: no DEF USE or cssClass, for example.

Probably best approach will be to handle them similarly to ROUTEObject.

Have added appropriate typing and also generated relevant run-time validation tests.

Tested sat in latest build.  Excerpts from updated HelloWorldProgram.java follow:

===================================
http://www.web3d.org/specifications/java/examples/HelloWorldProgram.java

String            inlineSceneDef = "inlineSceneDef";
InlineObject         inlineScene = new InlineObject(inlineSceneDef);
IMPORTObject     importStatement = new IMPORTObject();
EXPORTObject     exportStatement = new EXPORTObject();

// Inline/IMPORT/EXPORT validation testing (cannot be self-referential or may cause recursion error)
inlineScene.setUrl("someOtherScene.x3d");
importStatement.setInlineDEF(inlineSceneDef).setImportedDEF(worldInfoDEF).setAS(worldInfoDEF + "2"); // overloaded DEF test sat
exportStatement.setLocalDEF(worldInfoDEF);
scene.addChildren(inlineScene);
scene.addChildren(importStatement);
scene.addChildren(exportStatement);
===================================

this also led to some helpful thinking on X3D Security, issues posted separately.

Thanks as ever for the in-depth testing John.
