CompressionTests

@@ +1 @@
+I uncompressed the original file before starting, then did something similar to the following:
+
+fpack -h -s 1 -S dark > dark.fits.1 
+
+I did this for a variety of different scales ( 1, 2, 4, 5, 6, 8, 10).  The scales in the images are the following:
+
+|| 1 || 2 || 4 || 
+|| 5 || 6 || 8 ||
+
+I chose a number of different images to test- flat, dark, qtfocus, video focus, stare, moonglint, and an md01.  The md01 is just to see what happens to data we care about, in case we find out data we care about happens to be misclassified for some reason (PR images? other unknown things?)  The stare I chose happened to be not too interesting, but I included it anyways (I randomly picked files).
