cd directly to a folder

jd-nav defines shell functions that cd around a Johnny.Decimal system. Works in bash 3.2+ and zsh.

p76              # cd to the system root
p76 11.11        # cd to an ID
p76 tripsy       # search all IDs for a word, cd if a single match

It requires the standard config file: see configuration.

The code and documentation is at cli.johnnydecimal.com. I won't repeat it here as I'll just forget to update it.
