Added a new Algorithm to check if a number is prime or not. (#487)

Browse Source 
* Added a new Algorithm to check if a number is prime or not.

Added a new Algorithm to check if a number is prime or not. It takes one + half the amount of iterations of the square root of the number. Returns Boolean value.

* Fixed possibility of being truncated

Changed the 1/2 with a 0.5

* Fixed Major Error

Instead of 3, 5, 7 The Loop as checking 2, 4, 6 which would cause all odd numbers to show prime. Fixed by subtracting one.

* Fixed Minor Formatting issues

Github Merged the 2 previous and current version to make a weird file.

* Fixed possibility of being truncated

Changed the 1/2 with a 0.5
