Villager Selector

This is an idea i just came up with. It's currently on the first stage, aka the bare essentials. What it is: a contraption where you can select the villagers you want in your village by what they are wiling to trade. Currently all that is in place is: reject all lever, accept all lever (with accompanying trapdoors), and structure.
The second stage will be to add a reject/accept lever for each villager
The third step will be to add a villager placer so you don't have to keep using eggs (and therefore be in creative)
The last step is to make it look pretty =D
Feel free to enjoy the map, yes the house was indeed buried
