mapp.layer.decorate()
Decorates a layer object with additional properties and methods.
A mapview must be assigned to the layer object in order to decorate a layer.
The layer decorator passes the layer to a defined format method which assigns the Openlayers layer object (L).
Common interface methods such as layer.show, and hide are assigned to the layer object.
A blank layer.filter object will be set if the filter has not been defined in the JSON layer.
The first theme from the layer.style.themes array will be assigned as layer.style.theme if not already set.
Any plugins matching layer keys will be executed with the layer being passed as argument to the plugin method.
The layer object is returned from the decorator.
