There’s quite a few Google Analytics plugins available, some with a lot of bells and whistles.  I wanted one that simply took my Tracking ID, and inserted the Google Analytics JavaScript, so that’s what this does.  It saves a Tracking ID, and inserts the GA code into the blog via the wp_head() hook.  It does nothing else; no bells; no whistles; no secret added code or privacy issues.

Code can be found on GitHub.
