Jd major release available

[Eric Iverson]

Jd major release available.

Previously Jd focused on single user with direct access. Server facilities for multiple users over a network were limited and restricted to http.

This release is focused on Jd server:
 libcurl/curl - client https connections to node task
 node task    - local/remote connections to clients
 zmq          - http connections from node task to Jd server tasks
 Jd task(s)   - run Jd requests

Jd server supports secure logon user/pswd tables with encrypted passwords.

New batch and transaction ops provide better performance where network delays dominate.

Any client (for example, python) that can use libcurl/curl can securely and efficiently access a Jd server.

*** caution!!!

If you run Jd with load'jd' for serious work, create a private copy of your code base before it is changed by a pacman update.

Casual use is OK from pacman folder (pacman can update to new code)
   load'jd' NB. ~addons/data/jd is fine for casual use
   
Serious use should have a private folder (copy ~addons/data/jd to ~/production)
   load'~/production/jd/jd.ijs' NB. load production Jd
