Have supercollider work recursively

[loremipson]

Right now it seems that if I have markdown files inside subdirectories, they are ignored by supercollider. It would be nice if it would create the same file and directory tree that my pageRoot has.

I'll see if I can get a pull request for this in.. I can work around what I'm wanting to do in a different way, but having supercollider do this is more ideal.

My apologies. It seems like it does try to run on subdirectories, I was just missing the description from my front matter.

However, supercollider is still failing to create the files:

Error: Handlebars error: Cannot read property 'replace' of undefined
    at Supercollider.module.exports [as build] (/node_modules/supercollider/lib/build.js:21:11)

I haven't been able to look into this too far yet.
