adding information about genome, that particular chromosome is located on
added method for synteny block creation (_create_sb method needs to be rewritten in terms of reader supplied data)
added check for empty result in get_sbs_between method
changed method get_two_closest_mappings to produce position of looked up sb in returned list, as we'll need it in the future
added information about chromosome, that particular sb is located on
added information about genome, sb is located on, by property lookup in respective chromosome
added info about manager, particular genome is managed by
added resolution info to particular genome instance
added _add_chromosome _create_and_add_chromosome and add_sb method, as add_sb is a pipeline for adding sb, while _add_chromosome and _create_and_add_chromosome are used, when adding synteny block on some chromosome for the first time
added get_mapping_and_offset method, which return names of synteny blocks in different resolution, this block is mapped to range between and the position of it in this range
initial take on manager class, which works as an entry point for every activity
add_sb is most important method for information construction addition
get mapping_set_for_sb returns a set of blocks, looked up sb is mapped from res1 in res2
