The goal of TA1 is to collect and craft enough XYZ Ingots
to be able to build machines for stage 2 (TA2).
1. You have to collect dirt and wood to build a Coal Pile.
    (The Coal Pile is needed to produce charcoal)
2. Build a Coal Burner to melt iron to steel ingots.
3. Craft a Gravel Sieve and collect gravel.
    (A Hammer can be used to smash cobble to gravel)
4. Sieve the gravel to get the necessary ores
