Improve title of generated documentation

[benmccann]

The title on the docs right now look like "Radar · GitBook - Chart.js", which is what shows in Google. Not everyone knows what GitBook is, so it might be better if this showed up in Google as "Radar - Chart.js documentation"

I'd like to fix this issue. However, could anyone tell me where the text "Radar · GitBook - Chart.js" is?
I searched all the project, but can't find it.

Thanks.

See http://www.chartjs.org/docs/latest/charts/radar.html. The title is "Radar · GitBook"

@wmzhong you will not find the "GitBook" title text in the repository because it's handled by the GitBook generator. You need to look the GitBook API to see how to customize it (if possible) and inject our own title template.
