Description

We have a RouteText processor built for 0.4.0. This is very powerful but a very common use case will be routing and grouping CSV data. This use case, we can make the configuration far easier by creating a RouteCSV Processor instead of requiring the user to enter complicated Regular Expressions.

For instance, rather than a Grouping Regular Expression, we should provide
a Grouping Fields property where the user can simply enter a comma-separated list of CSV fields (numeric or perhaps column header names?)

Also, rather than comparing user-defined rules against a line of text, the rules could be compared against a specific CSV field.
