Name: Prime square remainders
Let pn be the nth prime: 2, 3, 5, 7, 11, ..., and
let r be the remainder when (pn−1)^n + (pn+1)^n is divided by pn^2.
For example, when n = 3, p3 = 5, and 43 + 63 = 280 ≡ 5 mod 25.
The least value of n for which the remainder first exceeds 10^9 is 7037.
Find the least value of n for which the remainder first exceeds 10^10.

* Fix style of the first ten solutions for Project Euler
- Unify the header docstring, and add reference URLs to wikipedia
or similar
- Fix docstrings to be properly multilined
- Add newlines where appropriate
- Add doctests where they were missing
- Remove doctests that test for the correct solution
- fix obvious spelling or grammar mistakes in comments and
exception messages
- Fix line endings to be UNIX. This makes two of the files seem
to have changed completely
- no functional changes in any of the solutions were done
(except for the spelling fixes mentioned above)

Reason:
The change was done to maintain consistency throughout the directory
and to keep all directories in sorted order.
Due to the above change, some config files had to be modified:
'problem_22` -> `problem_022`
* Update scripts to pad zeroes in PE directories
