Performance logging

[tischi]

@NicoKiaru

For debugging, teaching and benchmarking I think it would be great if one could add optional logging to the CellLoaders.
My idea is that in the user interface one could set a Logging Level to Debug (or Benchmark) and then would get such information: imglib/imglib2-cache#16

What do you think?

Never done that, but why not ? Are you sure it does not impact performance when off ?

I think there is so much code in the loaders that one
if ( Logger.Level.equals ( Level.Debug ) )
should not matter.

If you like the idea I think it could be already very interesting for the NEUBIAS seminar, because this would nicely demonstrate how you lazy load from big files.
