Add Code Formatter

[joneubank]

Detailed Description

Java based Overture apps have been using fmt-maven-plugin to provide standardized code formatting to their code bases. We should add this to Score and update formatting of all files across the code base.

Possible Implementation

Ego is currently using:

            <plugin>
                <groupId>com.coveo</groupId>
                <artifactId>fmt-maven-plugin</artifactId>
                <version>2.8</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>format</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
