I think the example code should be changed, since it looks like MouseData does not exist. The only things I've found are MouseRawData and MouseMoveData.
Thanks for letting me know about this, I've gone ahead and fixed that in the readme.md file and I'll take another pass through on the demos repo to be sure this has been revised.
