Used as a main program, this can refactor any number of files and/or
recursively descend down directories. Imported as a module, this
provides infrastructure to write your own refactoring tool.

For compatible patterns the bottom matcher module is
used. Otherwise the tree is traversed node-to-node for
matches.
Args:
tree: a pytree.Node instance representing the root of the tree
to be refactored.
name: a human-readable name for this tree.
Returns:
True if the tree was modified, False otherwise.

|S )a Refactors a docstring, looking for doctests.
This returns a modified version of the input string. It looks
for doctests, which start with a ">>>" prompt, and may be
continued with "..." prompts, as long as the "..." is indented
the same as the ">>>".
(Unfortunately we can't use the doctest module's parser,
since, like most parsers, it is not geared towards preserving
the original source.)
