Sometimes trace fitting fails for stars near edge of the detector. #13

For example, the last star in this WD1145+017 field seemed not to work: genericfinderchart.pdf

The solution is probably to trim the rectangle of pixels extracted around each star more dramatically. Right now, this takes place at the level of the input ".obs" file, but ultimately it should go into an instrument definition for each particular grating setup.

I think we took care of this with the restructuring, and with more care in the background/trace fitting.
