const FChunkDependencyTreeNode * BuildChunkDependencyGraph ( int32 HighestChunk )	Will create a dependency tree starting with RootTreeNode.	Commandlets/ChunkDependencyInfo.h
int32 FindHighestSharedChunk ( const TArray< int32 >& ChunkIDs ) const	Given a set of chunk Ids will use the dependencies to find which chunk is shared among all the given chunks.	Commandlets/ChunkDependencyInfo.h
void GetChunkDependencies ( const int32 InChunk, TSet< int32 >& OutChunkDependencies ) const	Returns the chunks that the in chunk depends upon through the parent rules.	Commandlets/ChunkDependencyInfo.h
