Function to get stateSave data directly

Hi,

First of all, I wanted to thank you for your excellent work on this library. I've just started using DataTables, and I really love it. It's obvious that you've put an incredible amount of effort into this library.

Here is my question. Is it possible to do something like this: var data = api.getSaveStateData(); This would return an object with all the relevant data to save into localStorage (or where ever).

On a page with multiple widgets, it would be nice, to store all the data for the page in one localStorage key (rather than 1 key per widget).

// Save state of all widgets on page close
var pagedata = {
    widget1: widget1.getSaveStateData(),     // Some widget
    widget2: widget2.getSaveStateData(),     // Some other widget
    dataTable: api.getSaveStateData()           // A DataTable
};
localStorage["mykey"] = JSON.stringify(pagedata);   // Save it all in one key

Then, on page load, you would pass the relevant data into the widgets as initialization options.

I think the main benefit is getting the page save / load logic centralized in one place rather than spread around. Particularly if your state saving strategy involves AJAX, then it seems like it would be much better to save / load the page state with one request, rather than one request per widget. Another benefit to storing all the data in one key is a unified expiration time for all the page data, so that you don't end up loading a partially-initialized page where some widgets' data has expired and others not.

Is this something that is already possible, or maybe an easy change?

Thank you,
James
