Drives
The drive acme (collaboration:/sites/acme) is created along with the site.
The project needs to create another drive to store a taxonomy tree. That drive is named powers (collaboration:/sites/acme/categories/powers).
	This drive creation is carried by ManageDriveService. 
	See 
	acme-drives-configuration.xml
Namespaces
	The namespace acme is created by configuring RepositoryService. 
	See 
	acme-namespaces-configuration.xml.
Nodetypes and templates
	In Products and Contact Us pages, you see contents of two types: 
	acme:product and acme:contact_us.
Each content type needs a nodetype definition, a dialog to create/edit and a view to display the content.
	For acme:product type as example, the nodetype is created by configuring AddNodeTypePlugin in 
	
	system-configuration.xml.
	The plugin reads nodetype definition in 
	
	nodetypes-configuration.xml.
The templates (dialogs and views) sources are written in gtmpl under this folder, and configured in nodetypes-templates-configuration.xml.
Actions and scripts
In the navigation, when you hover over the Products, you see a sub-menu dropped down. Any item of the sub-menu is a child node in the taxonomy tree powers.
	When you add a child taxonomy to the tree, it is automatically populated as an item to the sub-menu. 
	This population is carried out by the PopulateToMenu action.
The action is registered by xml configuration in dms-actions-configuration.xml.
This action is a script action and the source of the script is PopulateToMenu.groovy, that is registered in dms-scripts-configuration.xml.
