* Initial commit of the object mother iluwatar#498

Add a simple king and queen classes which implement the behaviour of the
royalty interface. Also wrote the object mother of royalty objects which
is final so you can just call the static methods in it to create objects
with a specific state to use them fast in tests. The tests are already
created for testing the behaviour and the type of the objects which are
created by the object mother.
I also created the UML diagrams via object aid and updated the readme.

* Add PlantUML file for the UML diagram iluwatar#498

* End process logic clause has been corrected.

* Unused import removed.

* Add SonarQube.com badge

* iluwatar#502 Replaced usages of System.out with logger.

* Change name of variables in test iluwatar#498

* add entry to parent pom.xml iluwatar#498

* Fix pom.xml

* Fix pom.xml

Deleted </modules> tag because i added it one time more than neccessary

* checkstyle errors removed

checkstyle errors removed

* iluwatar#502 Reverted changes in composite example, due to nature of this example using logger isn't good idea

* Remove use of coveralls-maven-plugin (sonarqube.com covers this)

* iluwatar#502 Adjusted tests for logger introduction

* iluwatar#502 Introduced logging in new example

* Create presentation template

* Link Hexagonal Architecture pattern to corresponding blog entry

* Work on Hexagonal Architecture presentation

* Add new diagram

* Add presentation link to README.md

* Update App.java

The relationship between decorator and target (in the code example between Troll und SmartTroll) ist not a composition as described in the code comment lines of class App. It's a aggregation. In a composition both instances canncot live without the other one. But the target (Troll) could live without the decorator (Smart Troll). Changed "composition" to "aggregation" in the comment lines. Code lines are unchanged.
Greetings Thomas
