lower bd for a variable
upper bound for a variable
lower and upper bounds for a row (these can not be handled separately at the moment)
direction of the optimization (is_max() function)

More sophisticated warning messages.

Some combined maps will be reference map if the first

to give a refernce map as first map but there is a non

to a regular read-write map.
