Purposes

• Explanations of what code does.
• Explanations of what mixins do and where they are placed.
• Explanations of math and what it's intended to do.
• Explanations of where code is vanilla copy.

Details

• Code explanation.
• Class explanations can be put in place of methods for small classes where necessary, like packets.

Will likely dedicate time to this after the package organization/cleanup.

putting this here before i forget: code in AerogelStairsBlock#hidesNeighborFace is based off of code in Block#shouldRenderFace
