/**
* Manages the compilation of an <fb:js-string> node, which
* is designed to inline the declaration and initialization of
* a new Javascript string variable. In a nutshell, the idea is for
* something like this:
*
* <fb:js-string var="myName">Jerry Coopersmith</fb:js-string>
*
* to render to something like this:
*
* <script type="text/javascript">
* a<app-id>_myName = "Jerry Coopersmith";
* </script>
*
* The implementation is careful to prevent the use of nested <fb:js-string> tags, and
* provisions are also made to support the one-dimensional arrays, as outline
* on the FBML Wiki.
*
* @param node the FBMLNode modeling the <fb:js-string> tag.
* @return a HTML string that helps define a new Javascript variable on the fly, where
* the new variable is set equal to the full rendering of the <fb:js-string>'s
* children.
