 MultiOBJective function for SOLAND function (constrains as objectives)

 This function implements the SOLAND test function.
 It features a convex objective function of two variables subject
 to a nonlinear equality constraint. The variables are bounded.

 The function is implemented with two objectives. The first 
 is the main objective, the second the equality constraint.

 Syntax:  ObjVal = mobjsoland(Chrom)

 Input parameters:
    Chrom     - Matrix containing the chromosomes of the current
                population. Each row corresponds to one individual's
                string representation.

 Output parameters:
    ObjVal    - Column vector containing the objective values of the
                individuals in the current population.
                if called with Chrom == [NaN, NaN, xx], than see objfun1 for options
