Add a " utils.input() " in python

[ThomasRitaine]

Feature Use Case

In games such as Akinator (which is partially implemented in this PR #143 ), we need to ask questions to the user. However, we can not ask the user to say "Yes" or "No", because it will go through the classical way of treatment, and the query may be send to a different module from the one that wanted the user to say "yes" or "not".

Feature Proposal

The creation of a method "input()" into the "utils" python object could fix this issue. The module that wants an answer from the user use utils.input() and it gives back the query with entities.
