Handles file uploads.
Simple example:
this will create a nt:file node below "/home/admin" if the node type of "admin" is (derived from) nt:folder, a nt:resource node otherwise.
Filename example:
same as above, but uses the filename of the uploaded file as name for the new node.
Type hint example:
this will create a new node with the type my:file below admin. if the hinted type extends from nt:file an intermediate file node is created otherwise directly a resource node.
