return only nodes which match the given pattern

Details

Note: IDs are a thing internal to this R package. They are not imported from or exported to actual ISA-tab files. However, given that the node 'identifiers' (e.g. 'Sample Name') can be ambiguous, IDs are necessary to unambiguously identify a node.
