removed file doc string
added check for retrieving fragment by sb id, as it might be located not on the outer-most position; information about gluing operation where sb is not outer-most block on respective fragment in the original data, such information would be ignored
added check for the case, when retrieved fragment, by sb id, contains such sb in the outer-most position on this fragment, but the direction doesn't match; information about such gluing operation would be ignored
changed the behaviour of -c/--chain option, as now if provides formatting for glued fragments, when two or more glued glued pairs share at least one fragment, such pairs will be formatted together as a appropriate chain
added -g/--glued option, which does exactly what -c/--chain option did previously
added --omit-genomes-names option for prevent output of genome names to the resulted output stream
