* iterative and formula fibonacci methods
Added two ways to calculate the fibonacci sequence: (1) iterative (2) formula.
I've also added a timer decorator so someone can see the difference in computation time between these two methods.
Added two unittests using the slash framework.
* Update test_fibonacci.py
* remove inline comments per Contributing Guidelines
* Update sol5.py
* Create placeholder.py
* Update and rename maths/test_fibonacci.py to maths/tests/test_fibonacci.py
* Delete placeholder.py
* Create __init__.py
* Update test_fibonacci.py
* Rename Maths/lucasSeries.py to maths/lucasSeries.py
* Update and rename Project Euler/Problem 01/sol5.py to project_euler/problem_01/sol6.py
Current implementation is buggy and hard to read.
* Negative values were raising a TypeError due to `math.sqrt`
* 1 was considered prime, it is not.
* 2 was considered not prime, it is.
The implementation has been corrected to fix the bugs and to enhance
readability.
A docstring has been added with the definition of a prime number.
A complete test suite has been written, it tests the 10 first primes, a
negative value, 0, 1 and some not prime numbers.

* organized graph algorithms
* all graph algorithms in Graphs/ folder
* all graph algorithms are in one folder
* Rename number theory/factorial_python.py to maths/factorial_python.py
