- Added LayoutLocation class
- Added RegionAddPeerLocCommand class
Note: still need to plumb through peer locations to UI JSON.

+ * </pre>
+ * When rendering the rUK region, the rES peer region node should be located

+ * <pre>
+ *     region-add-peer-loc rUK rES 100.0 200.0 grid

+ * When rendering the rUK region, the rES peer region node should be located
