Netzke::JsonArrayEditor

Abstract GridPanel-based editor for a JSON array of homogenious objects. Inherit from it in order to override: 

  <tt>store_data</p> - passes the data to be saved (e.g. to the persistant storage)
  <tt>initial_data</p> - should return initial data (e.g. from the persistant storage)

For an example of an implementation, see Netzke::FieldsConfigurator.
