In HCOSMIC, change temporary filename from hncosmic*list to tempcosmic*list
In HLIN, change temporary filename from hlin* to temphlin*
Add rvsao.rvrelearn to hrelearn, and because there is an added parameter
in rvsao.cl to make the new rvrelearn work in RVSAO 2.6.7, things break
unless both packages are upgraded.
In HCOSBAD, avoid dividing by zero (2008-10-28)
In HCOSMIC, give null string value argement to HEDIT when deleting keywords

Revise gains in HPROC, GAINCORR and HGAIN1 after Nelson Caldwell recomputed them
Version 3.5.3 (November 5, 2007)

which are too blue to see the red leak.
Version 3.5.1 (September 26, 2007)
Added parameter to hskyproc and hskylist so objects can be chosen to be on
one chip or the other and fixed a bug in hskyproc so that the correct sky
database is used when using skysame is no.
Upped maximum number of lines from 4608 to 4700 in hcosbad.x and hcoslim.x
Add debug parameter to hcosbad
Version 3.5.0 (September 12, 2007)
