class_docstr: This class can be used to fetch NuPic configuration settings which are
  stored in one or more XML files.
  
  If the environment variable ``NTA_CONF_PATH`` is defined, then the
  configuration files are expected to be in the ``NTA_CONF_PATH`` search path,
  which is a ':' separated list of directories (on Windows the separator is a
  ';'). If ``NTA_CONF_PATH`` is not defined, then it is loaded via
  pkg_resources.
docstr: Return the list of paths to search for configuration files.
  
  :returns: (list) of paths
