Memoize any function with this lightweight decorator, even across runs. It stores results in memory and disk.
The decorator makes use of the Pickle module to store (and retrieve) function results in a local cache folder.
Memoization is sensible to the function input arguments and source code, if any of these change the function gets executed and its output cached.
