Split tables into separate ports based on row partitioning

Demonstration of Create Partition Column component to split a table up into n partitions, and then chain the Regex Multi Row Splitter to output each "partition" on a separate port.

This is much quicker and easier than using a series of Row Splitters since each Regex Multi Row Splitter can output 10 results and then on the remaining 11th port can output the remainder to be picked up by the next Regex Multi Row Splitter in turn.

Each Multi Row splitter is configured with the partition number for each port.
