Touch | lrf.touch

The Little Robot Friends have 3 capacitive touch sensors on their face board: the hair sensor, the left hand sensor and the right hand sensor. Please note that the left and right orientation is from the perspective of the robot. Each sensor is capable of sensing 3 types of interactions, the first being a "tap" which is a single touch on the sensor pad. The second type of interaction is a "tickle", this is multiple touches in quick succession

Functions called from within the "touch" portion of the library have the prefix of lrf.touch
