Integrates FreshTags functionality into WordPress...

‘Categories by Tag Table’ allows you to display all your Categories as rows and Tags as columns in a html pivot table. 
Once activated it will replace the text ‘[CATS_BY_TAGS_TABLE]‘ in any post or page with a table. 
Each cell displays the number of published posts that are in both the category and have the tag, and a URL link to those posts. 
It might be a useful way to list your content for navigation or embed as a menu.
The options menu allows you to: 
* specify whether Categories are rows with tags as columns in the table or vice versa; 
* specify the title text displayed in the top left cell; 
* specify the url to your own CSS stylesheet to customise the styling to match your site; 
* specify what to show in any empty cells; 
* specify any charicters to remove from your Tag & Category names;
