 Creating Map Objects

 SunPy Map objects are constructed using the special factory

+Using Map Objects
+-----------------
+
+Once a map object has been created using `~sunpy.map.Map` it will be a instance
+or a subclass of the `~sunpy.map.mapbase.GenericMap` class. Irrespective of 
+the instrument the map is constructed for, all maps behave the same and are 
+interchangeable with one another. It is possible to manipulate the map or access
+meta data about the map from the methods and proprties of the map class.
+The following documentation of `~sunpy.map.mapbase.GenericMap` lists the 
+attributes and methods that are availible on all Map objects.
