##
# Build a method that a new customer will use when entering our deli.
# The method, take_a_number, should accept the current line of people,
# along with the new person's name, and return their position in line
# (and no 0 index, these are normal people, if they are 7th in line, tell them
# that, not 6).
##
# Build a method now_serving. This method should call out (via puts) the next
# person in line and remove them from the line.
##
# Build a method line that shows people their current place in line.
