Added the ability to pass in the function that walks the directory path, which allows for alternate implementations or supplying a mock function that provides values completely unrelated to the OS. This is available only from the API and not from the command line::
files = ["CVS/error.py",
for dir, file in FileSet(include="*.py", walk=walk_from_list(files)):
print dir, file
Fixed #10: Paths like //network/dir caused an infinite loop
Fixed #11: Incorrect handling of globs ending /** and /. Ant Glob semantics for::
are that they should match "all files that have a test element in their path, including test as a filename."
