 *
 * Functionality of Sketch:
 * Non Blocking
 * Detect Short or Long Button Push with fast and slow LED flash rates respectively
 * Quick Flash / Short Button Push has a shorter run duration than Slow Flash / Long Button Push
 * Create condition that if a flash is running a new button push is not actioned
 * Serial Print all actions
