Swing Panel Nest

关于parameter panel制作：
1，丛次：最外层---Layout:borderLayout.center(paramPanel)
           ---customPanel(包含paramPanel,并将paramPanel放到JScrollPanel中。设置parameterChanged)
              
     次外层---Layout:分为两层panel,外层：FlowLayout.leading, 内层：GridBagLayout---
           ---paramPanel:内层分别为三个titleBorderPanel,外层包含三个titleBorderPanel

     最内层---layout:GridBagLayout,titleBorderPanel
Code Following:

    public void initialise(Hashtable parameters, Hashtable inputDescriptors) {
