== Billboard TOP100 aggregation example

=== Introduction

The `billboard_lyrics_1964-2015` CSV dataset contains the TOP100 songs
with lyrics for each year.
We can compute the TOP20 artists with most songs on Billboard using
Split and Aggregate EIPs.
Build statistics is not the Camel core business but, as shown, you can
easily do it!

This is the final result:
