  * All this classes are registered as a service with the tag "chamilo_course.tool" here:
-
  * src/Chamilo/CourseBundle/Resources/config/services.yml
  *
  * The register process is made using the class ToolCompilerClass:
  *
  * src/Chamilo/CourseBundle/DependencyInjection/Compiler/ToolCompilerClass.php
-
  * The tool chain is just an array that includes all the tools registered in services.yml
  *
  * The tool chain is hook when a new course is created via a listener here:
-
  * src/Chamilo/CoreBundle/Entity/Listener/CourseListener.php
-
  * After a course is created this function is called: CourseListener::prePersist()
  * This function includes the called to the function "addToolsInCourse" inside the tool chain.
-
  * This allows to create course tools more easily. Steps:
-
  * 1. Create a new tool class here: src/Chamilo/CourseBundle/Tool
  * 2. Add the class as a service here: src/Chamilo/CourseBundle/Resources/config/services.yml  (see examples there)
  * 3. Create a new course. When you create a new course the new tool will be created
