[development] nodify.module idea: 'everything is a node'

My personal rule in this area is that if it is content then it is a node.

So things like users, categories, and yes I have have had someone say 
for E-Commerce 'a transaction should be a node', which are not content 
should not be a node.

The only thing that is borderline is a comment, as sometimes a comment 
can actually be content. but the overhead of a node for a comment really 
makes it impractical.

Also building a one size fits all box for every type of object really 
means that there will be overheads in areas which are not needed for 
some types of objects.
