I have a matrix (1000 x 224) that contains the output from the function 
boot.array.  For each row, there are 224 columns that represent the case 
numbers of the selected individuals from a bootstrap.  The cases are listed 
in selection order, not numerical order.  I'd like to rearrange the cells 
so that every row has the column entries listed ascending numeric order.

I've been able to do the sorting using two explicit for loops, but I cannot 
figure out a vectorized way to do it using apply, order, and/or sort.  Is 
there a clever vectorized way to do this?
