 The datalayers contains data, and a layer (a way to represent them).
 
 Each data layer contains a "layer", to know what type of layer it is. It's one of:
 
-- Choropleth (`L.U.Layer.Choropleth`)
-- Cluster (`L.U.Layer.Cluster`)
-- Heat (`L.U.Layer.Heat`)
+- Choropleth (`U.Layer.Choropleth`)
+- Cluster (`U.Layer.Cluster`)
+- Heat (`U.Layer.Heat`)
 
 When the data layers are initialized, they can have two states:
 - `loaded`: the object is loaded in memory. At this stage we have access to all the datalayer's metada (name, type, id)
