Add examples for flavored Markdown

[michaelrog]

Question about markdown, particularly about calling the flavors: Can you add an example calling markdown and a particular flavor on the markdown doc?

I see lower down on the page it says parsedown is an alias for for markdown(flavor='gfm').

Is that the right syntax? i.e. If I want a particular flavor, I need to write is as markdown(flavor ='gfm-comment') or markdown(flavor='yii-extra'), otherwise, just markdown on its own defaults to the 'original' flavor?
