The utils unit contains utilities that are useful to everyone. Things like rbtree, enabled, string, etc go here. This helps prevent clutter in the top level common directory. Also by organizing source code into these top level units we reduce our SWUD burden: all utility code may be described by one SWUD instead of many tiny SWUDs.
