[x3d-public] X3DPSAIL no need to wrap simple types; PyJNIus issues isolated; work next on native Python package

Let's not remove anything yet while refining design, but tuneups of stylesheets/java subdirectory entries that match your separate-branch improvements are welcome.

We still need to refine the syntax for pythonic keyword arguments and contained elements as the python package evolves.

Thus all the examples will change.  Nevertheless when we update the design document, we will likely want to document each of the candidate syntaxes are explored so that various alternatives are well explained.

Thanks John.

rephrasing my point with strictly measurable terms: a syntactically correct fragment is possible but this one is not valid, not renderable, and not a complete model.  Thus not very useful for basic design but certainly an edge case to consider for thoroughness.

YMMV, whatever works.

i think we will be glad later that we didn't remove anything until final syntax has emerged, with documentation all caught up and thorough.

all the best, Don
