Re: another shared object problem

This function can be useful when a user wishes to create
a common min/max/interval that will be used for
many plots [eg, for paneling].
Also, there is a contributed.ncl function ("symMinMaxPlt")
that uses the function to get symmetric contour limits 
[eg: -14 to +14] for use when using, say,  BlWhRe color map.
