"""
Problem 5 (30): Write a program (C++, C#, Java, Python) that parses a file and for each string it finds
(strings are separated by whitespace) outputs the string and which of the above languages it is a member of.
If the string is not a member of any, then it outputs 'none'. For organizational reasons, make a boolean
function for each of the languages. Please provide appropriate and helpful comments.

Example Run:

    File: test.txt
    Abcde: Id
    aAa9: Id
    3422222: Num
    ;: Semicolon
    wHile: Id
    while: Id, While
    &&: And
    8eo: none
    &: none
    ;asdf: none
