[X3D-Ecosystem] PythonSerializer.js broken in X3DJSAIL

[Don Brutzman]

John, there is no PythonSerializer.js in X3DJSAIL.

X3DJSAIL offers several ways to create corresponding Python source:

   - command-line invocation -toPython
   - https://www.web3d.org/specifications/java/X3DJSAIL.html#CLASSPATH
   - example invocation in HelloWorldProgram.java:
   -
   https://www.web3d.org/specifications/java/examples/HelloWorldProgram.java

ConfigurationProperties.setXsltEngine(ConfigurationProperties.XSLT_ENGINE_SAXON);
> // default

System.out.println ("Create Python source of model using stylesheet " +
> ConfigurationProperties.STYLESHEET_PYTHON);

savedFileName = thisSceneName + X3D.FILE_EXTENSION_PYTHON;

savedFile = x3dModel.toFilePython(savedFileName);

   -
   https://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/Core/X3D.html#toStringPython()

These conversions operate by serializing the in-memory Java model to an X3D
file, and then applying a conversion stylesheet.

   - org.web3d.x3d.jsail.ConfigurationProperties.STYLESHEET_PYTHON   =
   "X3dToPython.xslt"

all the best, Don
