crce-artifact-finder-script.py

# This script will walk directory tree of crce project and
# prints artifact ids of all poms it will find in following format:
# filepath: parentArtifactId -> currentArtifactId for artifacts with parent
# filepath: currentArtifactId for artifacts without parent
# Implemented method is compatible with Python 2.2 - 3.4
