Question about DEBUG statements

[Jon Schewe]

I've been doing some debugging with the QFX import matcher and noticed
that I needed to uncomment the DEBUG log statements and build a new
binary to enable these. I would have expected to just need to enable
the debug log statements on the command line with "--log
gnc.import=debug". 

I'm adding some more in an upcoming PR and want to understand which
ones should be commented out and which ones should not.

What is the reason that these statements are commented out?

Thank you,
Jon
