@**********************************************************
* Twirl YangTemplate for generating yang snippets.        *
* Twirl is transformed to Scala and compiled. Then,       *
* it can be called from Java with particular input        *
* parameters to render desired output code.               *
*                                                         *
* Note: we should introduce our own format instead of txt *
