coco .. degrees to/from Sumerian
------------------------------------------------------------------------

Many search programs prefer decimal degree input. But many astronomers
like to use Sumerian system (hms or h:m:s). coco comes to the rescue.


$ coco -d 18:00:00 30:01:02   # convert to degrees 
270.0000000  30.0172222

$ coco -d 18h00m00s +30d01m02.2s
270.0000000  30.0172222

$ csGAIA -r 20 -s $(coco -d 18:00:00 30:01:02)    #how convenient!!
