tokens, which for now is still completely built before parsing can proceed.
For each top-level block, the source start/end positions are added as

* Removed var from es in es.js to allow node.js to access it as global. Only
alternative solution appears to be a node-specific 'exports' construct:
http://nodejs.org/docs/v0.3.1/api/modules.html
* Added es.Document.js and es.Document.Serializer.js in es/bases. Not sure if
this is the desired location.
* Changed es.extend to es.extendClass in the serializers
* Modified the first parser test to include the WikiDom modules and call the
new HTML serializer
