Hi. I'm very excited about Gelly's Scala API. I'm reading the changes from
this PR. I found a problem about re-formatting. Unlike Flink's Java code,
Flink's Scala code use 2 spaces as indent. But I think the IDE did re-format
all code to use 4 spaces as indent.
We should preserve the previous indent setting to preserve modification
history.
