* be automatically merged and their coordinates removed.
* The scores, if any, will be averaged for the block, weighted by the corresponding block sizes.
* The pass value will be removed if it is different for the two blocks.
* It is possible to define a maximum distance for the merging. Setting a distance of zero implies that the blocks
* have to be exactly contiguous. Alternatively, the appropriate number of 'N' will be inserted in all species.
* All species however have to be distant of the exact same amount.
