support for activity diagram

[heni1]

The support of activity diagrams would greatly enhance this project.

Is this extension planned?

@heni1 I've been thinking about it as this is definitely very useful and also possible to achieve using Clang's API - however it is not planned for the immediate future, as I have a lot of issues to resolve with the already supported diagram types.

This is something I might schedule for 0.4.x series, which I was planning to release by the end of the year.
