What does parse_line( ) return and who consumes it?

[dougli1sqrd]

I guess it's used in AssocsParser, in parse(), but what is it that parse_line() is building up? And then who consumes the assocs array in parse()? I see that in ogr-parser-assocs.py uses it but then only the report is looked at, and the assocs array seems to be thrown out. We could make the dictionary that parse_line() returns some kind of class/object so that it's easier to read what it's place is maybe?
