"""
A pangram is a sentence that contains every single letter of the alphabet at least once. For example, the sentence "The
quick brown fox jumps over the lazy dog" is a pangram, because it uses the letters A-Z at least once (case is
irrelevant);

Given a string, detect whether or not it is a pangram. Return True if it is, False if not. Ignore numbers
and punctuation;
