/**
 * 
 * This class will be instantiated multiple times, using
 * the two different constructors with different semantics: constructor
 * ScriptingAction(frame) opens the project-wide scripting-dialog, while
 * constructor ScriptingAction(frame, FrinikaScript) will provide an action that
 * immediately executed the specified script.
 * This action is used to build the "Tools/Scripting" sub-menu.
 * 
 * Although this inherits AbstractMidiAction for implementation reasons, the
 * use of scripts generally is not restricted to modifying midi events, so
 * this class is located in package com.frinika.sequencer.gui.menu.
