  +Personally, I think that the *feedback control* topic is very promising for a lot of problems
  +in computer systems today and I assume, most of the software engineers don't know about it,
   although they use *feedback control* everyday without even noticing it
   (toilet flush? car cruise control? room temperature control? ...). At least for me this was true since 2015.
   
  
positive.code: Since I wasn't familiar with python and I usually work on the JVM
  with Java 7/8 and http://www.groovy-lang.org/index.html[Groovy],
  I thought it would be nice to have the code in a for me more familiar language.
  Also by porting it (and sometimes writing unit-tests for it), I became more familiar with the examples and to a deeper understanding of the topic.
  
  I also thought it would be nice to be able to change the code
  and see the resulting chart in the same "environment" with one tool.
  Therefor the groovy console with the http://www.jfree.org/jfreechart[JFreeChart] integration.
  
  And last but not least, I think I'll do some more work in this field, thinking of experimenting instead of "just" simulating
  with e.g. a dynamic sized thread-pool which adjusts itself to a given CPU load factor. With real threads,
  real runnables, etc... For this, a lot of this code here comes handy.
  
  
  
negative.code: ----
  
  This will build the project, download all dependencies and startup the slightly modified http://www.groovy-lang.org/groovyconsole.html[groovy console].
  Run the code with the "Execute Groovy Script" Button in the toolbar. Open the examples via the "Open Groovy Script" Button in the toolbar (and yes, select one of the java-Files).
