JSON Sitemap

[MuchDev 161]

Hey guys, I know this isn't really a how to, but I am currently working on a system to inline above the fold css and was needing a json pagelist, and figured I would write something to automate it. I included the ability to flatten the tree or keep it expanded. There is also a filter section where you can exclude individual pages by path, parent, id, or template. This is all pretty bare bones and will pretty much just gives you a json array of your page paths, but that is all I needed. This is working code but you will need to clear out the filters for your own site.
