the idea is to provide a map with different layers(e.g. earth population, atomic power plants, wheat growing acreages, sunrise or what you want)
and markers(events, demos, friends, anything, that is intersting for you).
These layer and markers should be importable and deletable by the user.</p>

#jquery.mapquery.mqLayerManager.js
The file containing the mqLayerManager Widget
### *$('selector')*.`mqLayerManager([options])`

####**Description**: create a widget to manage layers

- **map**: the mapquery instance
- **title**: Title that will be displayed at the top of the
layer manager (default: Layer Manager)
>Returns: widget
>Requires: jquery.mapquery.legend.js
The mqLayerManager allows us to control the order, opacity and visibility
of layers. We can also remove layers. It also shows the legend of the layer if
available and the error messages provided by the legend plugin. It listens to
layerchange event for order, transparancy and opacity changes. It listens to
addlayer and removelayer events to keep track which layers are on the map.
