In this initial build, several functions are available on the Novel object: word_count, which is self-explanatory word_frequency, which returns a hash containing key value pairs of the 'word => number_of_times_that_word_appears_in_the_text' variety word_find, which takes a string as an argument and returns the number of times the string appears in text. most_common_words, which returns each of the words that is the most common or tied for most common. All functions are case-insensitive and ignore punctuation.
