Focus Program

[Tom Droege <tdroege@veriomail.com>]

I just discovered that my focus program is not doing what I thought it was 
doing.  I thought that I designed it sot that it went into the stop and 
came out for each move.  It turns out that it was just incrementing from 
the last position.  This is bad from a stiction standpoint.

The the focus exposure now looks better with the stars lining up in a 
straight line.

I found this out testing MIKE.  I am close to moving it out on the porch 
and looking at stars.
