Xtion + openframeworks + Raspberry Pi

I apologize in advance for the possible unintelligent questions I might ask.
I am working on a senior project that requires me to pull PGB-d data from the XTion. @gepatto seems to have excelled in this respect.
I am working with an Overclocked raspberry pi 2 and have sucessfully complied OpenFrameworks.
My first question: @gepatto can you share with me the file you shared with @m_tsourma? Thank you
Second: Where do I find the ofxOpenNIGrabber and how do I integrate it into OpenFrameworks.
