Add support for number ranges about wit

[MokhtarKhorshid]

What would you expect to happen if the user says a number that's outside the given range? Or did you mean you want it to resolve to a range?

I want to have a number entity, for example from the sentence more than 90 seconds. This currently just picks out 90 as a number, for which I can't declare a range. It'd be good to have it behave like wit/amount_of_money does, where you can do less than $5 and it picks up the range and currency.

hey @PAK90, this isn't supported at this point. But like wit/amount_of_money, wit/number is supported by Duckling - so feel free to take a stab at it and submit a PR! One caveat is that many other dimensions are built on top of the Numeral dimension, so we'd need to move the implementation of ranges from that higher dimension to the lower one.
