Support new natural inspired algorithm - Grey Wolf Optimizer (GWO)

Title:
Support new natural inspired algorithm - Grey Wolf Optimizer (GWO).

Objective:
To Support GWO algorithm in jMetalCPP Core.

Motivation:
Based on NFL theorem (no free lunch theorem). There is no meta-heuristic best suited for solving all optimization problems. So, NFL makes this field of study highly active. Hence motivate me to add GWO to the core algorithms in jMetalCPP framework.

Hi @adajani .

Thanks for your contribution. I accepted pull request #14, but after that there is a conflict with #15.

Hi @ajnebro

The conflict appears on "JMetalInc/Algorithm.h". I noticed
#15 has remove the JMEtalInc folder
