class BaseTranslator(object):
    Base translator class. Instantiated for each node.
    indent_level says how far indented this node is. All nodes output without
    prefixing themselves with indent characters; only if they have a newline
    do they need to add them.
    module_name specifies the module prefix to append to all items in this
    node, if it contains any; it's lost as soon as you use sub_translate
    (since it's only needed for top-level things in modules)
    INDENT_STRING = "    "
