+/*
+
+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
