   RobotArmKinematics.cpp

   Contains the kinematics functions for the meArm robot arm
   See also: https://www.instructables.com/id/4-DOF-Mechanical-Arm-Robot-Controlled-by-Arduino

   Servo trims are chosen, so that 0°, 0°, 0° (left/right, back/front, up/down) results in the neutral position of the robot arm.
   Neutral means: pivot direction forward, and both arms rectangular up and forward
   Neutral position: X=0
                     Y=(LIFT_ARM_LENGTH_MILLIMETER + CLAW_LENGTH_MILLIMETER) - Here claw length is from wrist to hand PLUS base center to shoulder
