Add a default StdioAppender, with a SimpleTimerLayout, to
the root node. The activity levels of all nodes are set
via a property file with name=value pairs specified in the
following format:
name:
the actual logger name, in dot notation
format. The name "root" is reserved to
match the root logger node.
value:
one of TRACE, INFO, WARN, ERROR, FATAL
or NONE (or the lowercase equivalents).
For example, the declaration
tango.unittest = INFO
myApp.SocketActivity = TRACE
sets the level of the loggers called tango.unittest and
myApp.SocketActivity
