internal folio setup

Some "internal" folio documents set up as separate tabs (.pde files)
within the same project consisting entirely of block-commented text.
This will hopefully make it easy to document during development as the
files right there while coding - no need to open up something else.
Also, with plain text files, git will track changes better between
commits.

Scanned paper sketches will still need to be stored in an external
folder.
