Configuration file and other extensions

[wsw70]

Hello - great work, thanks for sharing.

I was wondering whether you are interested in expanding your site generator, or leaving is as it?

I am asking as I will fork it and make several changes:

• make the content delimiters {{ and }} configurable as they clash with Vue.js
• add the capacity to generate some indexes from the HTML / MD code to be fed to a search component.

I would be happy to make PRs for these but I am not sure about your plans for long-term maintenance.
