DESCRIPTION:
  This script creates the base files needed for a Node.js project
  with standard settings.

BASE FILES (${#BASE_FILES[@]}):
$(printf "  %s\n" "${BASE_FILES[@]}")

OPTIONAL FILES (${#OPTIONAL_FILES[@]}):
$(printf "  %s\n" "${OPTIONAL_FILES[@]}")

ENVIRONMENT VARIABLES:
  CREATE_OPTIONAL_FILES=true    Create optional files

EXAMPLE:
  $0                        # Base files only
  $0 --optional             # Base + optional
  CREATE_OPTIONAL_FILES=true $0  # Base + optional
