* Draft cleanup of the folder definition mess * Move old startup * Fixup! broken hacky includes * Update Makefile * Update Makefile * Update Makefile * Bulk format * Who knew, header guards are a wise idea * Squash some sizing warnings * Drop broken usb stack * Fix BLE headers to be sensible * Cleaning up proper c styling * We have newer clang, it does bracketing now * Run clang-format brackets * We can drop the old messy bracket-checker with newer clang format * WiP formatter * Align grids of scripts by right side Massively easier to read in nearly all cases * Excempt the table for compression from formatter
