Added sample program for Motor Controller.

Sample uses joystick output to directly control a motor controller.
Added to C++ eclipse plugin with in same way as Java MotorControl
sample.

+/**
+ * This sample program shows how to control a motor using a joystick. In the operator
+ * control part of the program, the joystick is read and the value is written to the motor.
+ *
+ * Joystick analog values range from -1 to 1 and speed controller inputs as range from
+ * -1 to 1 making it easy to work together. The program also delays a short time in the loop
+ * to allow other threads to run. This is generally a good idea, especially since the joystick
+ * values are only transmitted from the Driver Station once every 20ms.
