* "steps": [
* {
* "prompt": "The name of the widget:",

* }
* }
* ]
* }
* </code>
*
* Concept in details:
*
* 1. Step: The interactive step, can be 2 types [step, confirm]
* 2. Operation: Only support 2 kind of operations by this version call and jump, for call
* operation, will call the method from callback, for jump operation, will jump to the step
* it set, like this {"jump":0}
* 3. Confirm Step: This step will prompt a question to user, and let the user to choose,
* use the condition part to add operation to the interactive console
* 4. Field: If step has this settings, will prompt to get the user input using readline, and set
* the input as field of the return object.
* 5. Default: If no input is there, use this as default value, support method call, like this !time,
* do not support arguments for this version
