BIGV file format

[Doug Simon]

Hi Alex,

At this point in time, there is no documentation of the format other than the code (including BinaryGraphPrinter[1]). What's more, we are currently changing the format to improve the encoding.

@Jaroslav: As part of the format changes, I think it wouldn't hurt to document the format (e.g., docs/BIGV.md).
