> When Giraph implicitly adds a vertex (e.g., during edge-based input or mutations), the
vertex value is created using reflection, so it is default-initialized (e.g., a double will
be 0.0).
> For some algorithms, the default value might be something different, or even need to
be read from the configuration at run-time.
