"""
The idea for this Kata came from 9gag today.here

You'll have to translate a string to Pilot's alphabet (NATO phonetic alphabet) wiki

Like this:

INPUT:
    If, you can read?

OUTPUT:
    India Foxtrot , Yankee Oscar Uniform Charlie Alfa November Romeo Echo Alfa Delta ?

NOTES:
    The set of used punctuation is .!?.
    Punctuation should be kept in your return string, but spaces should not.
    Xray should not have a dash within.
    Every word and punctuation mark should be seperated by a space ' '.
    There should be no trailing whitespace
