Container Example
==============
This example shows how to add a container to our screen.
A container is simply an empty place on the screen which
could be filled with any other content from a .kv file.

'''Create a controller that receives a custom widget from the kv lang file.
Add an action to be called from a kv file.

# loading the content of root.kv

'''Clear container and load the given screen object from file in kv
folder.
:param screen: name of the screen object made from the loaded .kv file
:type screen: str
