If do a fresh clone of your repository from github you get a wrong directory structure.
On windows its even impossible to clone.
The last commit what works is 371ada787c1b904bea4a.
I don't know what's wrong but currently its unusable.
By the way the wrong directory structure is in the download zip on moodle.org/plugins present too.
To reproduce it do as below:

1. do a git clone on linux and look on the directorys "report.clicktrail" and so on
2. do a git clone on windows and you will get a "fatal: cannot create directory at 'reportclicktrail': Invalid argument"
