Revisions:
Rev: 405
Function: realTimeInit
Changes: Fixed up the PlatformGML GML layer. GML layer only has options hash, not a parameters and options hash.
Also added hash option(displayInLayerSwitcher: false) to not display GML layer in the layer switcher.

There are 3 openLayers.Layer options I've added to the options hash:
LAYERURL: The is the link to the data provider. I use this in the tree control to make the check box text clickable.
GROUP: This is used by the layer tree to group the layers together in a parent/leaf arrangement. All like GROUPS end up under the same parent.
QUERYABLE: Specifies if a given layer is clickable for a GetFeatureInfo request. Will popup an Info icon next to the active query layer.
legend: Specifies the image file to use as the legend in the layer tree control.
