Partitioner

This annotator partitions tokens into blocks of a given size.

For example, it can be used to mark blocks of 100 words long, from the beginning of each turn, or mark/copy the middle 300 words of each topic tag, or mark blocks of one-minute intervals, etc. Leftover tokens can optionally be annotated or not. The label of each block is the number of tokens in it, so leftover blocks can be distinguished from full blocks.
