Functions
EMAPI.VectorLayer	The constructor of a new instance of the EMAPI.VectorLayer class.
addObjects	Adds new objects to the layer.
bringToFront	Brings layer on the top of displayed layers.
removeObjects	Removes objects from the layer.
clearObjects	Removes all objects from the layer.
setMap	Sets the layer on the map.
setVisibility	Sets layer visibility on the map.
count	Returns an amount of objects in the layer.
getBounds	Returns the rectangle’s coordinates of the current map view which include all layer objects.
destroy	Destroys an object of EMAPI.VectorLayer.
