/**
 * This interface gives actions an alternative way of receiving input parameters. The map will
 * contain all input parameters as name/value entries. Actions that need this should simply implement it. 
 * 

 * One common use for this is to have the action propagate parameters to internally instantiated data
 * objects. 

 * 
 * Note that all parameter values for a given name will be returned, so the type of the objects in
 * the map is java.lang.String[].
