Clone nodes in the Node list during iteration - massive speed up (57
seconds down to 7 seconds)
Logging entries in the class. Need to implement a custom
appender/discriminator to properly handle both the retrieval profile
name and the thread name in an appender output
Adjusted logging to include per-thread logging at the level of the root
logger.
Updated Preferences Guice module.
Update logging to rewrite log files instead of append (probably most
appropriate for client machines - may want to change this to be property
driven and then have optional includes for client-side or server-side
properties that change this behavior).
Fixed a couple of minor issues with the prrofiles and added the profiles
into git.
