Add an easy way to write output to a file.

[gruns]

Perhaps another shortcut parameter to ic.configureOutput().

one way to do it: #58 (comment)

snoop and pysnooper both do what's described in that comment. You can also pass a Path object. And if you pass a Path or string so that the file is opened for you, you can also pass overwrite=True which uses open(path, 'w') at the beginning to clear the file. Otherwise it appends to the file by default so that logs are preserved between runs.

I think there should also be a color argument. It's more discoverable than the current method and it means users can still have color no matter where output is written.
