Added methods to return whether the solenoids are engaged or disengaged

[Benmw99]

Made methods in subsystems that say whether the pneumatics are engaged or not.

Ben good Job. This will work as written, however you can simplify the code even further. You don't need the if-else at all in these functions, you can simply write this

boolean isEngaged() { return gripper.get() == Value.kForward; }

since gripper.get() == Value.kForward is a conditional statement it returns true or false (remember when we covered that in class?)

And so, it will automatically return true, if true, and false otherwise. I would recommend updating the code to be streamlined in this way, although what you wrote is correct and would work as well.

once you update it, re push and I will merge it in.
