Retrieve resource:
			- Issues an initial GET request
			- If 200, continues, 404, returns False, otherwise raises Exception
			- Parse resource type
				- If custom resource type parser provided, this fires
				- Else, or if custom parser misses, fire HEAD request and parse LDP resource type from Link header
			- Return instantiated pyfc4 resource

		Args:
			uri (rdflib.term.URIRef,str): input URI
			resource_type (): resource class e.g. BasicContainer, NonRDFSource, or extensions thereof
			response_format (str): expects mimetype / Content-Type header such as 'application/rdf+xml', 'text/turtle', etc.

		Returns:
			Resource
