Generic Projection Pursuit 
[OPTS, IDX, SPINDEX] = GPP(X, PPF, CLF, PARS)

 Inputs:
    (X): Data matrix
    (PPF): Function handle to projection pursuit function of the form:
        [V,FVAL] = F(X,PARS), where (V) is the optimal projection matrix, and 
        (FVAL) is the projection index
    (CLF): Binary Cluster assignment function of the form:
        CLUSTERS = F(V,X,PARS), where (clusters) is in {1,2}

 Output:
    (OPTS): Binary separator object of class GSEP
    (IDX): Binary assignment vector in {-1,1}
    (SPINDEX): Split index. By default equal to projection index (FVAL)
        If PARS.SPLIT_INDEX is empty SPINDEX=FVAL
        otherwise (SPINDEX) is calculated from the user-defined 
        function (PARS.SPLIT_INDEX(V,X,PARS))
