Profile Decorator

A decorator to profile the run time of functions/classes/modules along with an example to show its usage.

The profile decorator doesn't print the results in stdout. Instead, the results are sent to a file. The decorator accepts the following keyword arguments:

1. output_file (optional, default = None): path of the output file. If not given, the name of the decorated function is used.
2. sort_by (optional, default = 'cumulative'): sorting criteria that can be a str, SortKey enum, or a tuple/list of those.
3. lines_to_print (optional, default = None): number of lines to print. If None all the lines are printed.
4. strip_dirs (optional, default = False): whether to remove the leading path info from file names.

For those interested, I wrote this blog and explained different ways of profiling in more detail.
