示例1: ConvertToNestOpInput
// <summary>
// Convert a CollectOp subtree (when used as the defining expression for a
// VarDefOp) into a reasonable input to a NestOp.
// </summary>
// <remarks>
// There are a couple of cases that we handle here:
// (a) PhysicalProject(X) ==> X
// (b) PhysicalProject(Sort(X)) ==> Sort(X)
// </remarks>
// <param name="physicalProjectNode"> the child of the CollectOp </param>
// <param name="collectionVar"> the collectionVar being defined </param>
// <param name="collectionInfoList"> where to append the new collectionInfo </param>
// <param name="collectionNodes"> where to append the collectionNode </param>
// <param name="externalReferences"> a bit vector of external references of the physicalProject </param>
// <param name="collectionReferences"> a bit vector of collection vars </param>
