/**
 * Implement a Robot Program framework.
 * The RobotBase class is intended to be subclassed by a user creating a robot
 * program.
 * Overridden Autonomous() and OperatorControl() methods are called at the
 * appropriate time
 * as the match proceeds. In the current implementation, the Autonomous code
 * will run to
 * completion before the OperatorControl code could start. In the future the
 * Autonomous code
 * might be spawned as a task, then killed at the end of the Autonomous period.
