function [parent] = binaryMutation(parent,bounds,pm)
% Binary mutation changes each of the bits of the parent
% based on the probability of mutation
%
% function [newSol] = binaryMutate(parent,bounds,Ops)
% parent  - the first parent ( [solution string function value] )
% bounds  - the bounds matrix for the solution space
% Ops     - Options for binaryMutation [gen prob_of_mutation]
