Generic DSL for DialogFlow ES

A generic DSL for generating agents for Google dialogFlow ES

The syntax for the language can be seen in the examples hotelBookingTemplate.df, alarm.df and flightBooking.df.

An example which uses inheritance to support multiple systems in one program can be seen here:
