[Tutorial] Fastest 4x4 Vault door (0.3s opening 0.3s seamless)

I figured out a way of making a 4x4 vault door opening seamless in 0.3s and decided to make as small of design as I could. The inputting way I show after the tutorial isn't the only way you can do it, but it is 100% reliable and spam proof so I decided to showcase it. NOTE: At 6:18 I meant to rename the stone pressure plates to "any pressure plates", not "any slabs".
