Ideas:
1. Each module in bind10 can be treated as one class, and each class has its
instances.
2. class has some functions, both class and instance have its "attribute". 

The command of bigtool is used to control bind10, or get/set some attributes
of module class/instance, so command line syntax is like:
  <module name> [instance]  <command name> [, parameter]
