Provide function that outputs ratings for each service comprising the postrank

Currently there are three functions available in the plugin. One to create a preformated postrank label, one to output the simple number and one to output the colour. I think it would be great if there were some functions to provide the numbers of each metric that postrank used to rate the post

First you could have one function that will display all the metrics in a simple unorganized list, say postrank_metrics(). Add a specific class to the list to make it customizable and you're set.

Then you could have a bunch of smaller functions for each individual metric, in case owners are only interested in showing specific ones if they exist and or want more freedom in how to present them (change their labels, add links etc). You could have postrank_reddit(), postrank_digg(), postrank_digg_comments() etc, each of these returning a simple number as in the_postrank() function.

Cheers!
