Bugs and Suggestions for Improvement
Note that these are minor bugs not affecting the functionality of the algorithms and they will be fixed in the next version of the package

1. od_KL: options K=1 and L=1 do not work
          options K > N, L > n do not issue a warning
   (found by P.Somogyi)
		  
2. od_plot: missing right parentheses in the manual U <- eigen(diag(4) - 0.25 * rep(1, 4)
            X <- Fx[, 1:4] should be 2 or 3-dimensional, depending on the type of visualization
