Location change and missing cells

I updated the publish.js to use an external location for the wiki helper.  This allows a user to put the template outside the node_modules folder (which is rarely versioned).  I've updated the readme to explain how the layout should look, I've seen this type of structure with other templates (docstrap).

The cells that were empty were being labled as headers and throwing everything off, so I added spaces between the bars to create empty cells:  |  |  instead of ||.

Hope this helps.
