Test Items
The purpose of the test is to verify that the singleGraph constructor is working properly
i.e. it set's up the instance of the graph correctly. The methods to be used are: public SingleGraph(java.lang.String id, boolean strictChecking, boolean autoCreate, int initialNodeCapacity, int initialEdgeCapacity), public SingleGraph(java.lang.String id, boolean strictChecking, boolean autoCreate), public SingleGraph(java.lang.String id).
