/*

This is an experiment in using the Narcissus JavaScript engine

to allow Selenium scripts to be written in plain JavaScript.

The 'jsparse' function will compile each high level block into a Selenium table script.

TODO:

1) Test! (More browsers, more sample scripts)

2) Stepping and walking lower levels of the parse tree

3) Calling Selenium commands directly from JavaScript

4) Do we want comments to appear in the TestRunner?

5) Fix context so variables don't have to be global

   For now, variables defined with "var" won't be found

   if used later on in a script.

6) Fix formatting
