New Trajectory Auto Init Has NullPointerException

[stulewin]

The merged trajectory code into the climber branch has a problem with the instantiation of the auto commands in Robot.java.

I am going to comment out for now in the climber_sequence_impl branch so I can continue.

Here is the stack trace; since I don't understand it - I'll leave it to you. Is it a function of my laptop development environment?
