Think of a good representation of merge operations in the log file

[Reemh]

so far it only logs the resulted merged row/col in the modifier.

In the diff finder it logs the deleted rows/cols as "del" and the merged one as "merge".

So far the merge in the log has the following structure

operation	type	id	position	data
merge	column (or row)	col1+col2, col1, col2	pos_of_merged, pos1, pos2
split	column (or row)	col1, col2, col1+col2	pos_of_merged, pos1, pos2
