[CF-metadata] original_ensemble_size

Hi Mark,

I didn't quite understand how the standard name gets associated with a 
variable (containing 1 or more realizations from the ensemble). Someone 
said it was through a scalar coordinate variable, but I don't see how 
the ensemble member is a function of the ensemble size, so why would 
this be appropriate?

Could you supply an example?

Also, I didn't follow why "original" was included in "original ensemble 
size".  Surely, you wouldn't report this number unless you thought the 
ensemble size was pretty much set and wouldn't change. In that case 
there shouldn't be a need for a "modified ensemble size", so wouldn't 
"ensemble size" suffice?

thanks,
Karl
