示例1: MergeCycleWithoutMergeThrows
public void MergeCycleWithoutMergeThrows()
{
TestValue<string> vD;
var graph = new[]
{
TestValue.Create("A", "B"),
TestValue.Create("B", "C"),

};
var byValue = graph.ToLookup(t => t.Value);
var components = graph.DetectCycles(s => s.DependsOn.SelectMany(d => byValue[d]));
Assert.AreNotEqual(components.Cycles().Count(), 0);
var flattened = components.MergeCyclicDependencies().ToList();
