rename with name that comes out of irc discussion:

```
[15:08] <        zeus> | al: my biggest nit (which I didn't want to bring up in the demo) is the leaking of 
          'presentation' into the database layer.
[15:08] <        zeus> | al: but I don't have an concrete rebuttal for :D
[15:09] <@dgoodwin> i'm gonna rebut it
[15:09] <@dgoodwin> =]
[15:09] <@   dgoodwin> | al: zeus: i think it's just using the word is misleading, the actual data is 
                       sorting, limit, etc, it is 100% database specific
[15:10] <@dgoodwin> so you see a class/variable named presentation going to db
[15:10] <@dgoodwin> and think "whoah presentation layer is leaking to db"
[15:10] <        zeus> | dgoodwin: ok I think that's it
[15:10] <        zeus> | dgoodwin: that's what makes it feel dirty :D
[15:10] <@al> I can change the names if you have a suggestion.
[15:10] <        zeus> | I'm ok with Page because that's more like memory paging vs UI page
[15:10] <@al> I called it DataPresentation because Page was taken by the object the curator level returns.
[15:10] <        zeus> | al: filter comes to mind but that seems overused
[15:11] <@dgoodwin> everything we can come up with would already be used by hibernate, limits, filters,
