Safeout: write out a file safely

With safeout, you can write:

from safeout import safeout
with safeout('output.txt') as output:
    output.write("Hello world\n")

and this will write out the file output.txt in a safe, atomic manner. That is, if there are any problems (Exceptions or a crash) in the with block, then there there will be no output. If the with block completes, then the output file will include the whole result.

So, if the output file exists, you can be confident that the process completed correctly.
