"""
This module extend freeOrionAIInterface from python side.
Check that you have import of this module from FreeOrionAI.py


Adding to string:
=================

Adds object string methods to enable output as
{unique_object_prefix}{id}<{name}>
"P(1)<Sirius>" would be for the planet with id=1 and name=Sirius
This will help to track objects around logs.

str vs repr:
============

If you print item or %s it __str__ will be called if you repr, print list of items or %r __repr__ will be called.

Code organisation:
==================

keep fo.<attr> in same block

def planet_to_string():
    pass


def planet_repr():
    pass

fo.planet.__str__ = planet_to_string
fo.planet.__repr__ = planet_repr


Logger:
=======
wrap any fo function or method to logger to get more info about it.
don't commit logger wrapped function to repo.
