PlantUML diagram support in Markdown
Wanted to add PlantUML to the supported languages in Markdown to gain:
'''plantuml
for code fencing, with the difference that the output is not a beautified code, but a UML diagram. The PlantUML text (http://plantuml.com/PlantUML_Language_Reference_Guide.pdf) is replaced by the UML diagram's graphic.
This way we get the power of UML inside markdown documents without the cost of unmaintainable inserted graphics.
