Support for Iro

[ainslec]

Hello,

I'd really like to add support for Rainbow to Iro ( https://medium.com/@model_train/creating-universal-syntax-highlighters-with-iro-549501698fd2 ), which I think would be beneficial for both projects, but don't see that rainbow as demarcated context support (start regex patter, end regex pattern, inner context).

Can you tell me if Rainbow then is a sub-set of the Textmate style grammars, and if so, if it is impossible to directly map textmate concepts onto Rainbow.
