Not loading the mermaid javascript file properly

[mtrienis]

I am not seeing the rendered flow diagram from the example you provided in the readme.md. It seems to be a loading sequence issue because if I execute

mermaid.init(undefined, $(".mermaid"));

The diagrams start to render although the styles seem to be messed up.

This seems to be an issue with the initialization for newer versions of mermaid. I'm looking in to it via #5
