[IIAB] New IIAB VEnv Approach

[Tony Anderson]

Hi,

I can now access iiab via http://schoolserver/iiab using mod_wsgi and 
apache.

The next problem is to point the dataset to /library/knowledge

In XS-0.7, the /library partition has almost all of the disk space.
The intent is that all content and expanding directories (Journal 
backup) should be in /library. The root partition has 8GB.

I set up iiab.conf in /etc/httpd/conf.d as

XSendFile on
WSGIScriptAlias /iiab /var/www/html/iiab.wsgi
Alias /iiabstatic /library/knowledge

However, I get an error when I click on Gutenberg/books by author that
it did not find a database. Currently /library/knowledge has the sampler 
dataset but that may not be installed correctly either.

[root at schoolserver library]# ls -1 knowledge
gutenberg
INFO.json
khanacademy
openstreetmap
wikipedia-kiwix
wikipedia-zim

I am rapidly becoming an expert!
