Problems with indention

[yunqi10qiu]

Hi, I find that there are some problems with indent. For example, when I enter m.06w2sn5 (Justin Bieber) at the command line, the a screenshot of the output is as the following, and we can see that when a CVT code (m.0gxnnwp) links two different nodes (m.0gxnnwq and m.06w2sn5) with the same predicate (people.sibling_relationship.sibling), the two nodes have inconsistent indented characters, which may cause a misunderstanding.

In FastRDFStoreClient/Program.cs:221, they missed to insert indent spaces when writing a new line.
