Description

The tag currently only creates/references a global singleton version of the collection. We need to implement such that instances bound to the current controller can be created as well.

Proposed Syntax

Singleton

<!-- "src" is the Alloy Model on which the model is based -->
<Model src="myModel"/>

Instance

<!-- "src" is the Alloy Model on which the model is based -->
<!-- adding an "id" will implicitly make this an instance -->
<!-- "instance" can explicitly make the collection an instance -->
<Model id="someId" src="myModel" instance="true"/>

While a singleton would be made available in Alloy.Models, an instance model will be attached to the current controller just as a UI component. So the above instance model would be accessible in controller code like this:

var modelInstance = $.someId;
