[qqiumax]

Same as title, we need gtag.js than analytics.js of google analytics to stop the disaster as suddenly all of the data stops collecting.

Pull request #159 may fix that.

To use it in advance:

1. Go to the fork repo.
2. Copy _includes → head-custom-google-analytics.html.
3. Paste it into the _includes/head-custom-google-analytics.html in your own repo. (Create a new one if it doesn't exist)

This overrides the head-custom-google-analytics.html in cayman.

Equivalent:

> mkdir _includes
> curl https://raw.githubusercontent.com/YinAoXiong/cayman/master/_includes/head-custom-google-analytics.html --output ./_includes/head-custom-google-analytics.html

(working directory: where the _config.yml is)
