Added a couple comments and addition dialogue.

In the reset(), my hope is that the program

will actually wait until the Turret has reset

before displaying the next output message.
Changed the position of the phi and theta var.

Typically spherical coordinates are represented

as (rho, theta, phi), and I wanted to mirror that.
Added some comments about Missile Turret direction.

Under moveby in the Adapter class, I added comments

to reference what happens when phi or theta is

negative or positive.  Depending on the sign, the

Turret head will move accordingly.
