python script to automate docs gen

[jackparmer]

This first section of documentation pages was designed to be auto-generated if the node (code) exists but the documentation page does not:

(The description at the top would be pulled from the node function docstring, and the i/o parameters would be pulled from its parameter's manifest)

Most of the nodes in this repo currently do not have a docs page, so it would be a high leverage time to write this script so that it can be used by CI or anyone contributing a node in the future. (it will also help us ensure that every node has a quality docs string!)
