Loads NLM Lvg and Norm, reading configuration information
from a config (properties) file
Since the value of the LVG_DIR property in the lvg properties file
must be either a hard coded absolute pathname or the value AUTO_MODE,
and we want to support installing this project in a directory of the
user's choice, we avoid using a hardcoded pathname and choose to
use LVG_DIR=AUTO_MODE in the properties file.
