+/**
+ * A sequential array of linestyles.
+ *
+ * This is used for multiple objects within the same element with different line
+ * styles. This is done by adding multiple line styles to a LineArrray
+ * structure. The linearray will then when requested return the 'next' linestyle
+ * in sequential order. It is possible to specify ID tags to each linestyle,
+ * which is used to make sure some data uses a specific linestyle (i.e. in a
+ * multiple-/stackedbarchart you name the {@link Image_Graph_Dataset}s and uses
+ * this name as ID tag when adding the dataset's associated linestyle to the
+ * linearray.
