[x3d-public] X3DJSAIL: command line option to force output directory creation

[John Carlson]

See my code for loading a class from a classloader created from a jar URI.
  You'll probably have to do that in addition to a URI resolver to find the
jar within a jar.    Both sets of code have been posted under different
purpose. Consider using .jnlp's referencing .jnlp (web start).
