Exercise 10: project update!
as someone pointed out to me in the forum, the samples in the project template were not correctly formatted. I have committed an updated project template, with correctly indented samples and a small update to HTMLBuilder.addElement, removing two spurious newlines. Moreover, you do not have to implement Canvas.fillEllipse as has been discussed on this forum previously, so I removed this method from the template.
Sorry for the late update,
