Add empty values in logs

[tmigot]

Is it possible to insert empty values in log_row ?

The aim is that the empty entry would still be aligned with the other columns. This is useful, for instance, when printing logs for an algorithm that computes two different steps.

Not currently. There is no stored information about columns. I was looking into creating a logger structure to do this.

Would it be simpler if the user gives a Val{Float64} instead of an empty Float64? Then, the function row_formatter could put the right number of spaces.

It's worth a try. I'm finishing a draft of the logger structure, so we can compare approaches.
