Description

In several classes of the 'opennlp-similarity' sandbox component, commented System.out statements exist that have a debug statement flavor. Yet, in tests and at runtime those spam the console quite heavily. That's why those have been commented out during the compatibility migration towards tools version 2.1.x conducted for all sandbox components.

The aim of that issue is to convert those spammy log behavior by making use of the slf4j-api. The code contains the spots marked with a TODO notice and this issue number for which a switch to a logging framework with "trace" or "debug" levels could be considered.
