Write a function, anagram, that takes in two strings as arguments. The function should return a boolean indicating whether or not the strings are anagram. Anagram are strings that contain the same characters, but in any order.

anagrams('restful', 'fluster') # -> True

anagrams('cats', 'tocs') # -> False

anagrams('monkeyswrite', 'newyorktimes') # -> True

anagrams('paper', 'reapa') # -> False

anagrams('elbow', 'below') # -> True

anagrams('tax', 'taxi') # -> False

anagrams('taxi', 'tax') # -> False

anagrams('night', 'thing') # -> True

anagrams('abbc', 'aabc') # -> False

anagrams('po', 'popp') # -> false

anagrams('pp', 'oo') # -> false
