Sorting [was: Polygrid sorting]

[Alex Tweedly]

So it occurred to me, while playing with sorting by columns, that it 
might be nice to have an additional "sortType" available.

I'd like to be able to say

  - if all the 'things' being sorted on are numbers, then sort numeric, 
otherwise sort alphabetical.

Would that be a reasonable enhancement request ?

Would "natural" be a reasonable suggested name ?

Alex.
