/* Read all relevance information from text_qrels_file.
Relevance for each docno to qid is determined from text_qrels_file, which
consists of text tuples of the form
qid ujg docno rel
giving TREC document numbers (docno, a string) and their relevance (rel,
an integer between -127 and 127) to query qid (a string) as judged by user ujg.
Fields are separated by whitespace, string fields can contain no whitespace.
File may contain no NULL characters.
All <docno,rel> pairs stored in per judgment group per query arrays
within all_rel_info.
Each list of query judgments is sorted lexicographically by docno,
