/* Your task:

    Write a function that takes a string, removes the most common letter(s) across the whole string and prints the result, 

    one per line, in a rectangular frame (with a single space padding each side of the longest string). 

    For example the input "Hello, how are you doing?" gets printed as:

    *********

    * Hell, *

    * hw    *

    * are   *

    * yu    *

    * ding? *

    *********

    Stretch: Create a small Unit testing framework for this
