Correct Logging

[yves-amevoin]

As the designer is getting mature, we should think about logging when error occurs in the linelist.

When a user experiences an error in the linelist, we should be able to file a report on when the error occurs as well as the state of the computer when it occurs.
Since we are not in deep software programming, we can just think about simple statements to guide in the debugging process:

• The procedure where the Error occurs
• When the error occurs (the trigger event)
• Temptation of error causes
• The environment where the error occurs.
• A log to indicate the steps to reproduce the error
