Data point labels

Hi

First, thanks for the class. I dropped it into my cakephp project and was making graphs in minutes! Kudos!

Was wondering if you were actively maintaining though? If you are, would you consider adding support for Data Point labels? I think they're a new feature and are implemented with the "chm" operator: http://code.google.com/apis/chart/labels.html#data_point_labels

Thanks again,

Tom Wright

Also, I've made a small change that you might choose to incorporate in the next build.

Just added an extra parameter to printGraph to give the option to just return the image url, rather than echo the image tag.
