Add algorithm for testing Project Euler solutions (#2471) 
* Add file for testing Project Euler solutions

* Remove the importlib import

* Update project_euler/solution_test.py

Co-authored-by: Christian Clauss <cclauss@me.com>

* Small tweaks to project_euler/solution_test.py

* Test Project Euler solutions through Travis

* Improved testing for Project Euler solutions:

- Renamed file so that it isn't picked up by pytest
- Fail fast on validating solutions through Travis CI

* Update validate_solutions.py

* Use namedtuple for input parameters and answer

- Remove logging
- Remove unnecessary checks for PROJECT_EULER_PATH as Travis CI
  picks up the same path

* Fix flake8 errors: line too long

* Small tweaks to validate_solutions.py

* Add all answers & back to using dictionary

* Using pytest for testing Project Euler solutions

- As we want to fail fast on testing solutions, we need to test using
  this script first before we use tests written by the author.
- As pytest stops testing as soon as it receives a traceback, we need to
  use pytest-subtests to tell pytest to test all the iterations for the
  function with given parameters.

* Print error messages in oneline format

* Separated answers into a separate file:

- Add custom print function to print all the error messages at the
  end of all the tests
- Let Travis skip if this failed

Create problem_54 in project Euler (#2451) 
* Add solution and test files for project euler 54

* Update sol1.py

* updating DIRECTORY.md

* Fix: use proper path to open files

* Commit suggestions:

- Use list comprehension instead of map
- Sort imports using isort

* Changes made as suggested (simplified a lot):

- List and set comprehension instead of itemgetter
- Using enumerate as it's easy to read
- Divided into list of card values and set of card suit as set will
  remove all the duplicate values. So, no need for double indexing.
- Add test for testing multiple calls to five_high_straight function

* Add suggestions and simplified:

- Split generate_random_hands function into two:
  - First will generate a random hand
  - Second, which will be called, will return a generator object
