COLL Recognition I (H, Pi, T, U)

This is part I of my COLL recognition tutorial. I've received several requests for COLL algorithms, etc, over the past 6 months so I figured why not make a video tutorial. My algs (I think I changed 2) are here: https://docs.google.com/Doc?docid=0AWg-oMdOeacZZGM5bmR2Nl8yMTNmcmc1OHdjdg&hl=en Part 2 will finish off U, then move to the uglier cases in Sune, Anti-Sune, and L.
