/**
* This command group will be used in autonomous. Based on what position the

- * Google folder is a picture explaining each of the cases.
- *
- * dependency on sensors: lidars, encoders, gyro
- *
- * dependency on subsystems: drivetrain
- *
- * dependency on other commands: TurnForAngle(), DriveForDistance()
+ * robot is in, the robot will align with the goal
*
* pre-condition: robot is flush against a defense at the specified position in
