+/**
+ * A template-based insertion sort algorithm, but not really 100%
+ * generic. It is mostly written for lists, not for arrays.
+ *
+ * A good reason to use insertion sort over faster algorithms like
+ * heap sort or quick sort, is that it minimizes the number of
+ * movements of the items. This is important in applications which support
+ * undo, because the number of commands is kept to a minimum.
