_version added 0.1_

|
####**Description**: initialise MapQuery and associate it with
|
|
the matched element
|
|
|
|
**options** an object of key-value pairs with options for the map. Possible
|
|
pairs are:
|
|
|
|
* **layers** (array of MapQuery.Layer *or* MapQuery.Layer): Either an array
|
|
* or a single layer that should be added to the map
|
|
* **center** ({position: [x,y], zoom: z(int), box: [llx,lly,urx,ury]}):
|
|
* Initially go to a certain location. At least one layer (in the `layers`
|
|
* option) needs to be specified.
|
|
|
|
> Returns: $('selector') (jQuery object)
|
|
|
|
|
|
We can initialise MapQuery without any options, or for instance pass in a layer
|
|
object. The mapQuery function returns a jQuery object, to access the mapQuery object retrieve

|
the 'mapQuery' data object.
