Move example into the webix-meteor-data repo

Similar to https://github.com/webix-hub/webix-meteor-mvc/issues/3.

Right now this example duplicates the code from the webix-meteor-data repo.

Would it be possible to move this example under the webix-meteor-data repo? That way, we could symlink from the public directory to ../codebase/meteor-data.js and avoid duplicating the code.

@mkozhukh, it seems you have agreed to this idea a while ago, so I hope it's possible :)

Ping. I'm working on updating the Meteor package to use Webix 2.5.

The status right now is that:

• the Meteor adapter in this repo is obsoleted by the meteor-data adapter. The latter fixes at least two bugs.
• this example uses a non-recommended way of loading the adapter (via the public directory). The recommended way is to use the webix:webix Meteor package.
