[sudodoki]

If you have participant, whose name contain -, in sequence diagram, mermaid will fail with following message

TypeError: 'undefined' is not an object (evaluating 'action[0]')

Mermaid version is 0.3.0
Phantomjs version is 1.9.8

Been looking at this and it is a bit tricky to fix as the Hyphen is also involved in the signal type. It is possible to fix but would make the grammar much more complex. Perhaps we could encode it somehow?

[knsv]

Fix for this issue was released in mermaid 0.5.2. Will close this now, let me know if you issues still remain.
