Entities needed down the conversation

[xavieramoros]

I currently need some retrieved entities to be in the context to be used further down in the conversation, so exactly doing what "merge" used to do, merge entities into context, as seen in #103

I'm doing something wrong or is it expected that my code handles that situation?

Example: Asking for the weather of a location.
After message 1 I receive the date as an entity 'datetime'.
After message 3 I need that entity but it's gone from the context.

1-->User: What's the weather today?
      Entities: datetime = today
      Context: "Ask weather"

getWeather(context):

location & datetime	missingLocation	missingDatetime
Weather in {location} for {datetime} is {weather}	Where?	When?

                                                                 Bot: Where? <-2

3--> User: In Barcelona
         Entities: location = Barcelona
         Context: "Ask weather"

Jump to getWeather

                                   Bot: Weather is "Sunny with 20 degrees"<---4
