    paper.updateViews([opt])

Update views in a frozen `async` paper to make sure that the views reflect the cells' models; keep the paper frozen afterwards.

Several extra arguments may be provided in the `opt` object:

batchSize | number | For `async` papers, how many views should there be per one asynchronous process? Default is `1000`.

progress

function

Callback function that is called whenever a batch is finished processing. The callback function is provided with three arguments:

done | boolean | Are we done? Was this the last batch?
processed | number | How far along are we? How many elements have been processed as part of a batch so far?
total | number | How many views are there? How many elements in will have been processed as part of a batch when we are done?

viewport | function | Callback function to determine whether a given view should be added to the DOM. By default, `paper.options.viewport` is used, but you may provide a different callback function. The format of the callback method is described in the option's documentation, as are examples of usage.
