improves pylint score from 5.83 to 10.00.

fixes #7

…actor-unionfind

refactor(pylint): unionfind/count_islands.py

…actor-search

refactor(pylint): algorithms/search/*.py

Improves pylint score from 5.51 to 9.96.

Score is lower than 10 due to duplication between maximum_flow_bfs.py
and maximum_flow_dfs.py. However, due to the educational nature of this
repo, keeping it as is will probably be benefitial as it reduces
complexity while reading (having to jump between files).

fixes #9

a reason that lint score isn't 10.00 is that the module is called dp,
which in turn makes pylint raise invalid name for all files in dp.
I leave that as it is, since I don't want to mess with the current folder structure.
