Requirements
------------
Requires the watchdog framework:

pip install watchdog

Usage
-----

Start with:

python live.py <file_to_watch_and_run>

The given file will be immediately loaded and run, but the
program will not exit.

The file should be almost normal python code.
It should not have any infinite loops - ideally it should run
for a short time and then exit after setting some local state which
will be returned to the calling environment.

Now open <file_to_watch_and_run> in a text editor, modify it
and save the change.

The file will immediately be reloaded and executed.

"import" cannot be used. Instead do this:

modname = use("modfilename")

This will load the file "modfilename.py" and return it, similar to
import.

However, the imported file can be edited, and any changes will trigger
a reload and rerun of the calling script.
