+/**
+ * Directive to display share holder information in the yellowInfopage.vm. The
+ * layout is controlled by the css.
+ *
+ * The layout can be controlled by the following css elements:
+ *
+ * tabsheader - The table header rolestable - defining the overall gui for the
+ * table sh_left - Gui left Column sh_middle - Gui Middle Column sh_right - Gui
+ * Rigth
+ *
+ * hover_on - The gray color witch is every second row
+ *
+ * The way to use this would be: #shareHolder($company.getInfo(yproller)
+ *
+ * The format of shareholders is defines as : #aksjonaer0#
+ * #bold#Navn#sep#Eierandel i %#sep#Antall aksjer#sepnl#
+ *
+ * This class is not thread safe,,, must it be ?
+ *
+ * @See JiraIssue https://jira.sesam.no/jira/browse/CAT-497
