      *  A bunch of predefined `Simple Actions` used by IPython.
      *  `Simple Actions` have the following keys:
      *  help (optional): a short string the describe the action.
      *      will be used in various context, like as menu name, tool tips on buttons,
      *      and short description in help menu.
      *  help_index (optional): a string used to sort action in help menu.
      *  icon (optional): a short string that represent the icon that have to be used with this
      *  action. this should mainly correspond to a Font_awesome class.
      *  handler : a function which is called when the action is activated. It will receive at first parameter
      *      a dictionary containing various handle to element of the notebook.
      *
      *  action need to be registered with a **name** that can be use to refer to this action.
      *
      *
      *  if `help` is not provided it will be derived by replacing any dash by space
      *  in the **name** of the action. It is advised to provide a prefix to action name to
      *  avoid conflict the prefix should be all lowercase and end with a dot `.`
      *  in the absence of a prefix the behavior of the action is undefined.
      *
      *  All action provided by IPython are prefixed with `ipython.`.
      *
      *  One can register extra actions or replace an existing action with another one is possible
      *  but is considered undefined behavior.
