* Class AstroQuery
*
* This class is used in star catalog queries to specify which object(s)
* to search for.
*
* The class attributes specify the conditions for the search, such as
* id, name, position, radius, etc. All of the fields are
* optional. Fields are set to the appropriate null value, if they are
* not being used.
