[gradsusr] Get MAX value from every group of 6 values from data - Grads

[Jennifer Adams]

The amin()/amax() functions will give you the min/max over an area.  But it will return a single value for each set of 6; if you want to build a new grid out of that result you'll have to use 'gxout fwrite' and write the data file point by point.

I want to calculate the MAX value from every group of  6 values from data.  Simply, if I make group of every 6 values, I want to get max value from every group.
