The purpose of this script is to take a file from cc_files table, and insert it into
the schedule table. DB columns at the time of writing are
starts | ends | file_id | clip_length | fade_in | fade_out | cue_in | cue_out | media_item_played | instance_id
an example of data in this row is:
"9" | "2012-02-29 17:10:00" | "2012-02-29 17:15:05.037166" | 1 | "00:05:05.037166" | "00:00:00" | "00:00:00" | "00:00:00" | "00:05:05.037166" | FALSE | 5
