An implementation of GraphReaderWriter that reads/writes graphs from/to text
files. Each line of the text file represents an object to be modelled by
When performing a read, the text file is read line by line. As each line
is read it is tokenized based on the delimiter property, and passed to the
template method readInternal(StringTokenizer), which must be implemented
by a subclass. The method returns the object that is to be represented in
the graph. The returned object is then passed to an underlying GraphGenerator
which creates the necessary graph components to modell the object.
When performing a write, the graph is read component by component based
on set properties. If the NODES property is set, nodes will be written. If
the EDGES property is set, edges will be written as well. As each component
is processed, it is passed to the repspective template methods
writeNode(Writer,Node) and writeEdge(Writer,Edge). The methods then write
out the text representation of the component.

Performs a write on the graph out to a text file. If the NODES property
is set, the nodes of the graph will be written, and if the EDGES property
is set, the edges of the graph will be written.
