Chief Delphi - CommandBase not recognizing a subsystem's type

Our team is using the CommandBasedRobotTemplate and when we try to create the static declaration of a subsystem in Command Base we get an error that states

Code:

C:/WindRiver/workspace/CommandBasedRobotTemplate/Subsystems/../Commands/../CommandBase.h:23: error: ISO C++ forbids declaration of `Drivetrain' with no type

C:/WindRiver/workspace/CommandBasedRobotTemplate/Subsystems/../Commands/../CommandBase.h:23: error: expected `;' before '*' token

The way to fix the issue involves forward declaring the class if you include commandbase.h in your subsystem.
