I am seeing Green Coffee Bean extract advertised everywhere now (including Starbucks.) It apparently is some sort of fat burner or something. Does anyone know what this stuff exactly is? Is it Paleo?

Assuming that it does work, and that's not an assumption I actually share, it's been claimed that it works on the same pathways as doing low carb, or restricting carbs.
So, why spend money on something you can do yourself, for free, by simply omitting tons of carbs? Go lower carb, or do IF, you'll get the same effect, and a lot more benefits.
Here's an explanation: http://www.lef.org/magazine/mag2012/abstracts/feb2012_Green-Coffee-Bean-Extract_04.htm
Yeah, green coffee extract is this years raspeberry ketones or garcinia cambogia -- it contains a substance that might be helpful in supporting or suppressing some bodily process related to fat burning or storing.
The problem with these supplements is that they "work" -- meaning they do "support" (likely at least) the processes the advertisers claim they support, however, the advertisers tie up the claim with "... and lose X lbs, fast!", which is generally the 100% bunk part.
Products like these aren't generally helpful. Even slightly more effective natural supplements for weightloss, like thermogenic ones, only assist with weight loss a small bit. In all cases, they are not going to cause weight loss -- they support an otherwise healthy lifestyle, which includes plenty of physical activity.
Summary: don't but the green coffee extract unless your dying of curiosity -- you will be disappointed.
The jury is out on its efficacy. The "study" that was done does not even come close to being an accepted study.
Still Mark Sisson says its Primal (#LetsNotArguePrimalvsPaleoToday), but unsure of it's advantage to regular brown coffee:
I used three bottles of this stuff and saw no results :P Then again, everyone is different, and some may have better results than others.
I am also interested in green coffee extract and have been doing some diggin around. This Doctor Oz seems to be saying good things about it in his TV show. The case study done by him in his TV show here http://www.youtube.com/watch?v=u0mqeq6EeJ8 seems to be pretty convincing. I may give it a try based on the results some of those women have seen in that video.
