code: public void addSection(final Section SECTION) {
          sections.add(SECTION);
          init(getInnerBounds().width, getInnerBounds().height);
          repaint(getInnerBounds());
      }
docs: Adds a given section to the list of sections
  The sections could be defined by a start value, a stop value
  and a color. One has to create a Section object from the
  class Section.
  The sections are stored in a ArrayList so there could be
  multiple. This might be a useful feature if you need to have
  exactly defined areas that you could not visualize with the
  track feature.
