Elementary cellular automata (#1302)

Browse Source 
* feat: Added Elementary Cellular Automata Algorithm w/ explanation, examples, and further reading

* test: Added tests for Elementary Cellular Automata Algorithm

* chore: add Wikipedia link to Elementary Cellular Automata Algorithm

* Used | Bitwise OR and ^= (Bitwise XOR) operators in calculating next Elementary Generation over Addition + and Subtraction -=
