This plugin registers with the prepareChain and for each entry it adds a \$wc metadata variable. The wordcount is sort of an expensive process since it requires the data of the entry to be populated and we only populate that on-demand. Thus we need to populate the \$wc variable on-demand as well.
The effects of this is that I can add a \$wc variable to my story.html template file and you see a wc: thing on all of my entries.
This plugin and the entry that describes this plugin were written, tested, and documented in 15 minutes.
