* include variables and .h files as pp directives * start layout compilation * split ergodoxes up * don't compile all layouts for everything * might seg fault * reset layouts variable * actually reset layouts * include rules.mk instead * remove includes from rules.mk * update variable setting * load visualizer from path * adds some more examples * adds more layouts * more boards added * more boards added * adds documentation for layouts * use lowercase names for LAYOUT_ * add layout.json files for each layout * add community folder, default keymaps for layouts * touch-up default layouts * touch-up layouts, some keyboard rules.mk * update documentation for layouts * fix up serial/i2c switches
