Change models
+ Added new kind of meta-heuristics: math-based and music-based
+ Math_based:
* SCA - Sine Cosine Algorithm
+ OriginalSCA: The original version
+ BaseSCA: My version changed the flow
+ Music_based:
* HS - Harmony Search
+ OriginalHS: The original version - not working
+ BaseHS: My version which changed a few things
* First I changed the random usaged of harmony memory by best harmoney memory
* The fw_rate = 0.0001, fw_damp = 0.9995, number of new harmonies = population size (n_new = pop_size)
