# Exercise: MacrosAndCodeEvaluation-2
# Write a macro called *times_n* that takes a single numeric argument. It should define a function 
# called *times_n* in the caller's module that itself takes a single argument, and that multiplies 
# the argument by *n*. So, calling *times_n(3)* should create a function called *times_3*, and 
# calling *times_3(4)* should return 12. Here's an example of it in use:
# 
# defmodule Test do
#   require Times
#   Times.times_n(3)
#   Times.times_n(4)
