function [c1,c2] = arithXover(p1,p2,bounds,Ops)
// Arith crossover takes two parents P1,P2 and performs an interpolation
// along the line formed by the two parents.
//
// function [c1,c2] = arithXover(p1,p2,bounds,Ops)
// p1      - the first parent ( [solution string function value] )
// p2      - the second parent ( [solution string function value] )
// bounds  - the bounds matrix for the solution space
// Ops     - Options matrix for arith crossover [gen #ArithXovers]
