I get it. Sure. Let's do that. Who knows, maybe someday JavaScript 
will be able to call getProperty and handle a Java object. One question:

Q: Won't the return for Java getProperty() be a generic Object, so 
that sometimes it's a string, sometimes a Hashtable, etc.? Maybe we 
will need, for JavaScript:

getStringProperty()
getJsonProperty()

so that JavaScript NEVER is allowed to call the generic Object 
getProperty() function.

Ah, I suppose so. Right -- we can run with what we have.


By the way, I realized just this morning the significance of HEAD and 
version. (I mean, I knew the difference, just didn't put 2+2 together 
this time.) DUH! Right, of course what I do on HEAD may or may not 
ever make into a version. Somehow I was thinking that "HEAD"s just 
automatically get turned into versions, but of course that's not true. 
  you can pick and choose what you want out of a HEAD to include in 
any next version. That I leave to you. (Still, I'm not going to commit 
this until I play with it a bit more and get more feedback.)
