remove duplicated function (because of its functionality):
def is_empty(iterable)
from package hra_core.collections_utils; 
use function hra_core.misc.is_empty as a substitute

add parameters named settings_package, settings_name in function
def get_application_settings(settings_package, settings_name)
in package hra_core.resources

change paths elements labeled as 'settings' to 'hra_resources' in files
icon.properties, settings.properties
of HRAResources project

add a new program parameter named --settings_package (-p) in
hra_core.globals.Globals class
used to specify explicitly package where an application settings
properties file is located
