Thanks to Lars Vandenbergh for Image Cube.

Thanks to Thibaut Jacquinot, Harris Chan, Shotaro Makisumi and Dan Dzoan (and future contributors) for helping me to build the F2L database.

And of course to the entire absolute team(Thibaut again alias "Thibaut", Jean alias "Jannot", Jean-Baptiste alias ..."JB", Edouard alias "Doudou", Thomas alias "Wheelup" and Clement alias "Keylie") for all the tips we shared to each other. Teamwork is the key!!!
