Detectar pangram

/*
	// 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.
