object MultiSeriesBlock extends Serializable

A MultiSeriesBlock groups multiple GorillaSuperBlocks in an indexed format. All the SuperBlocks are concatenated and there is a footer managed by thrift that contains the index and optionally names/string-keys for each SuperBlock.

The start and the end of the blob are marked with the 4-byte magic number 'STS\n': 53 54 53 0a that stands for "super time series".
