Package Class - StandardLayoutLocator is not visible.

[cinnamonforsf]

I have installed 'Cinnamon' managed package version 1.1 in Salesforce and when I try to access Apex class 'StandardLayoutLocator' that lives in this Package , getting the given below error during compile time

Error: Compile Error: Type is not visible: standardlayoutlocator.

Also can somebody provide latest API Document, currently using given below link: http://forcedotcom.github.io/cinnamon/docs/

But this link is not having updated classes, it is missing some classes like VisualforceTag.
