Initial release of MagicBot framework

[virtuald]

Magicbot has had a lot of upgrades this season, and hopefully in the offseason I'll be able to add some more things and document them.

Two particular new features in today's release that I wanted to highlight:

1. There is a 'tunable' property that you can add to automatically add variables to networktables (sorta like ntproperty, but less verbose)
2. Do you like the autonomous state machine builder? Of course you do! Well, you can create magicbot components using the same style of declarative state machine helpers!

As an example, here's a theoretical shooter component:

class ShooterAutomation:

    # Some other component
    shooter = Shooter
    ball_pusher = BallPusher
    
    def fire(self):
        """This is called from the main loop"""
        self.engage()
        
    @state(first=True)
    def begin_firing(self):
        self.shooter.enable()
        if self.shooter.ready():
            self.next_state('firing')
        
    @timed_state(duration=1.0, must_finish=True)
    def firing(self):
        """This state will continue executing even if engage isn't called"""
        self.shooter.enable()
        self.ball_pusher.push()

...
    
class MyRobot(magicbot.MagicRobot):

    ...
    
    def teleopPeriodic(self):
    
        if self.joystick.getTrigger():
            self.shooter_automation.fire()

If you're competing at the Championship, you probably won't want to upgrade. But for the rest of you, download it and give it a shot.
