ADS object query

This pipe runs an ADS object query for an astronomical object identifier over the publications of the current and the last n months (note the date format of "-n months"). The output stream is modified to hold "[Object]: Paper title" as item.title and "Paper author" as item.author. The abstract is stored in item.description This pipe is not intended as standalone, but to be run from a parent pipe, aggregating streams about scientifically interesting objects and topics (to the author, that is) into a single RSS-resource.
