Python/JavaScript bridge module, making use of Mozilla's spidermonkey

JavaScript implementation. Allows implementation of JavaScript classes,

objects and functions in Python, and evaluation and calling of JavaScript

scripts and functions respectively. Borrows heavily from Claes Jacobssen's

Javascript Perl module, in turn based on Mozilla's 'PerlConnect' Perl binding.
