New Workstation/Villager! The Minecart Station/Miner!

Basically, imagine a miner villager. You could trade him coal and sticks, so he could have torches, and you could trade him emeralds to get diamond, iron, etc. You could also get a copper helmet from him so that  you could block gravel and sand from falling on you. Do you have two full stacks of copper like me? Just trade them with the miner, and get emeralds!
