Compatibility bugs with some TSPLIB instances (soon corrected):
==> some instances have a space after a section title, for example "NAME :" instead of "NAME:".
==> several instances have the "COMMENT:" section before the "TYPE:" section.
==> several section are not yet implemented ("DISPLAY_DATA_TYPE:", ...).
Already corrected bugs:
==> some instances have several lines with the keyword "COMMENTS:"
For instance, the Berlin52 instance:
NAME: berlin52
TYPE: TSP
COMMENT: 52 locations in Berlin (Groetschel)
