class String
  # Add string function to handle WMI property conversion to json hash keys
  # Makes an underscored, lowercase form from the expression in the string.
  # underscore will also change ’::’ to ’/’ to convert namespaces to paths.
  # This should implement the same functionality as underscore method in
  # ActiveSupport::CoreExtensions::String::Inflections
  # @return [String]

      gsub(/([a-z\d])([A-Z])/, '\1_\2').tr("-", "_").downcase
