STK_MAXABSCORR computes the maximal absolute correlation for a set of points

 CALL: MAC = stk_maxabscorr (X)

    computes the Maximum Absolute (linear) Correlation MAC between the columns
    of the array X.

 NOTES:

    * The construction of experimental designs (more specifically, Latin 
      hypercubes samples) with a small MAC is considered, e.g., by Florian
      (1992) and Cioppa & Lucas (2007).

    * When X is a Latin hypercube sample, the linear (Pearson) correlation
      coefficients and Spearman's rank correlation coefficients coincide.
