Subject: [PATCH] Change how the library is exported

This commit makes the library define the |PEG| global variable (for
browser export) and possibly assign it into |module.exports| (for
Node.js export) later. The |module.exports| assignment is done *outside*
the main library |function| statement.

The big idea behind this is to make copy & paste inclusion of the
library into another code easier -- one just needs to strip the last
three lines.
