Description

Adding Template Resolvers for response generations

Motivation and Context

The ASK SDK handles request from Alexa Skill VUI by routing it to specific handler and builds up response to send back. Currently it uses ResponseBuilder to construct a response.

Template concept has been popular and powerful in web app development, where web designers and developers can work together to automatically generate customized web pages, by injecting dynamic content data into static template, which contains common components like header, footer, navigation bar etc.

Similarly, template concept can be introduced to Alexa Skill development, so that voice application designers and developers can work together to automatically generate customized skill responses
