Dealing with Skies

[holdengill]

Would be useful to have a skies tutorial, including:

must use 'take_skies=True' when establishing the instrument
config must only include the objects that have the skies (and of course the darks/flats)
skies files must be titled under 'Object' as the object they correspond to (ID #), with 'sky' in the 'Comments' column (cannot capitalize 'sky')

Errors usually come at registration - has no problem developing darks and flats.
