[Users] LayerContainer in TreePanel

[Matt Priour]

Julien,
Your method works fine. You would just change the root config to this
...
root:{
nodeType:'async',
children:[layerListTasmania,layerListUS]
...

alternatively you can use an async node for the parent of both the 
layerListTasmania & layerListUS in the treeConfig.
Since you are using filter functions, you have to define the treeConfig 
directly rather than round-tripping it through the JSON reader/writer.

ex:
...
{nodeType:'async',
children:[{
      text: 'Tasmania Layers',
      layerStore: mapPanel.layers,
      leaf: false,
      expanded: true,
      nodeType:'gx_overlaylayercontainer',
      loader: {
          filter: function(record) {
              return record.get("layer").name.indexOf("Tasmania") !== -1
          }
      }
 },
{
      text: 'US Layers',
      layerStore: mapPanel.layers,
      leaf: false,
      expanded: true,
      nodeType:'gx_overlaylayercontainer',
      loader: {
          filter: function(record) {
              return record.get("layer").name.indexOf("US") !== -1
          }
      }
 }]
}
...
