HAFAS returns notes for journey legs, stopovers and departures. There are two kinds of notes: "remarks" (in `remL`) and HAFAS Information Manager (HIM) notes (in `himL`). The former describe the regular operating situation, e.g. "bicycles allows", whereas the latter describe cancellations, construction work, etc. The planned naming scheme for hafas-client: - hints: notes from `remL` for regular operation - warnings: notes from `himL` for cancellations, construction, etc - remarks: both "notes" and "warnings" This commit prepares the new naming scheme by renaming the existing parsing logic of `remL` to "hints". Follow-up commits will add `parseWarning`.
