STK_SAMPLING_RANDOMLHS generates a random LHS design

 CALL: X = stk_sampling_randomlhs (N, DIM)

   generates a random Latin Hypercube Sample of size N in the DIM-dimensional
   hypercube [0; 1]^DIM.

 CALL: X = stk_sampling_randomlhs (N, DIM, BOX)

   generates a random Latin Hypercube Sample of size N in the DIM-dimensional
   hyperrectangle specified by the argument BOX, which is a 2 x DIM matrix
   where BOX(1, j) and BOX(2, j) are the lower- and upper-bound of the interval
   on the j^th coordinate.
