/**
* DefaultHandler implements a simple IOHandler that creates 'file'
* and 'folder' nodes. This handler will create the following nodes:
*
* - New Collection: creates a new node with the {@link #getCollectionNodeType()
* collection nodetype}. The name of the node corresponds to the systemId
* present on the import context.
*
* - New Non-Collection: first creates a new node with the {@link #getNodeType()
* non-collection nodetype}. The name of the node corresponds to the systemId
* present on the import context. Below it creates a node with name
* {@link JcrConstants#JCR_CONTENT jcr:content} and the nodetype specified
* by {@link #getContentNodeType()}.
*
*
* Import of the content:
* The content is imported to the {@link JcrConstants#JCR_DATA} property of the
* content node. By default this handler will fail on a attempt to create/replace
* a collection if {@link ImportContext#hasStream()} is true.
* Subclasses therefore should provide their own {@link #importData(ImportContext, boolean, Node)
* importData} method, that handles the data according their needs.
