Added new tutorial category for Remote Control, and the Basic Button Techniques tutorial Spelling fixes Added DriveBase remote control tutorial Added another remote control tutorial, for a basic DriveBase Fix typos and formatting Change remote image from PNG to JPG Use "not in" instead of "not (..in..)" Use "not in" instead of "not (..in..)" for better Python style Fixed tutorial md snippet to match the py update from the "not in" style fix Moved Remote Control tutorial category to be under Wireless Moved the Remote Control category to be under the existing Wireless top-level category, and changed the Remote Control category md file to specify layout: set so that the entire structure parallels that of wireless/hub-to-device
