function Forest=GlobalSeeding(candidate, Forest, Eval)

% This function gets the candidate population, the whole Forest and the evaluation function and
% performs global seeding on a percentage of candidate population
%
% Input:
%       candidate:  The candidate population from population limiting stage
%       Forest:     The whole Forest
%       Eval:       Evaluation function handler
%
% Output:
%       Forest: The Forest with newly added trees
%
