/*
    ExampleCommand

    Note: 
     1. You should include this class "After install" on the Custom panel.
     2. You must change this class to do whatever you want it to do. In the original form, it'
        trying to run a program called mySpecialInstallerExecutable. Of course, you'd want to
        rename this to whatever program you want to run and if the program isn't cross platform,
        address that in the section of the code marked by <-------> comment lines.
     3. You're welcome to adapt this class to use with a JExpress Installer or Updater.
