/**
* Implements the "Exclamation" program that attaches five exclamation mark to every line of a text files in a streaming
* fashion. The program is constructed as a regular {@link org.apache.storm.generated.StormTopology} and submitted to
* Flink for execution in the same way as to a Storm {@link org.apache.storm.LocalCluster}.
* <p>
* This example shows how to run program directly within Java, thus it cannot be used to submit a
* {@link org.apache.storm.generated.StormTopology} via Flink command line clients (ie, bin/flink).
* <p>
* The input is a plain text file with lines separated by newline characters.
* <p>
* Usage: <code>ExclamationLocal <text path> <result path></code><br>
* If no parameters are provided, the program is run with default data from
* {@link org.apache.flink.examples.java.wordcount.util.WordCountData}.
* <p>
* This example shows how to:
* <ul>
* <li>run a regular Storm program locally on Flink</li>
* </ul>
