+/**
+ * 
+ * 
+ * Support of a GroupAction could go a ways to simplify command line
+ * specification of actions to run. Instead of having to list actions to run one
+ * would simply end up referencing the group. In addition, this may end up
+ * opening up the possibility to customize the behavior of GroupActions such as
+ * not continuing to run actions if one failed. Currently, the crawler continues
+ * executing actions even if an action fails this could be a way to tailor that
+ * behavior.
