remove xstream from utils (not neeeded) and the only use, a clone method in a deprecated class
make clearer and simpler how logging should be set up, in a way friendly to downstream projects
ensure access to child locations is synchronized, to prevent ConcModExc
we can add appenders to root in the same file where the appender is defined, that's cleaner!
fix typo and improve syntax highlighting (including clipboard now) for logging.md
misc fixes to documentation
properly fix the syncing in AbstractLocation causing a ConcModExc -- all accesses now synced
code review comments, hopefully address some of the WTF's around logging!
