Title: Allowing to set tileLayers inside 'defaults' so that you can setup multiple layers for custom zoom levels.

I added support to allow this code to work:

$scope.defaults = {
layers: [
L.tileLayer([here the tile url]), {
maxZoom: 13,
minZoom: 0,
}),
L.tileLayer('[here the tile url]', {
minZoom: 14,
maxZoom: 18
})
]
}
