App structure definition

On this image, the mobile app structure is conceptually shown on Designer Studio:

The different components that make the app are shown on the image. Thus, the sequence for building is: 

1. Create Application with its Target setup, without a theme or start view. 
2. Create Layout with the corresponding visual areas. 
3. Create Theme for the app Look & Feel. 
4. Create the initial app Site View and assign a pre-created Layout. 
5. Assign the initial Start View and the pre-created App Theme. 
6. Create the View Instances for the pre-created Site View. 

Each of the related components will be dealt with on this documentation.
