Public Attributes
std::shared_ptr< DataFile >	file
	The file to lookup.
std::map< double, std::shared_ptr< FileLocation > >	locations
	A map of all locations where the file resides sorted with respect to their distance from the host 'host_to_measure_from'.
std::string	reference_host
	The host from which network proximity will be measured from. If 'host_to_measure_from' is host 'A', and the workflow file resides at hosts 'B' and 'C', then the proximity will be computed between hosts 'A' and 'B', and hosts 'A' and 'C' so that the locations of the workflow file may be sorted with respect to their current network proximity value.
