I will try to move it in a different module this week then.
TextImageReader is something that aim to be generic. It can parse file
in different locale (I sometime have files with coma instead of dot as
decimal separator), some columns may be something else than numbers
(e.g. a column may be a date), it make sure that every line have the
same number of columns, etc.
My intend was to merge the design of old text I/O with latest Simone's
one, but again I didn't had the time to start that work...
