7. Spoken summary on introductory page. (Easy.)

8. Smaller graphic on intro page so can see more of whole page at once. (Easy. Crop the bottom of the picture?)

9. Short demo on write or intro page. (Medium time. This would be the enhanced version of an auditory-only summary and may replace it or be a movie user can click on.)

The mostFrequentWords() function passes a string to the getTokens() function, which
splits it into an array of words, returning that to mostFrequentWords(), which saves 
it into the "words" array. mostFrequentWords() then tabulates each word in the array, 
storing the results in an object array called wordFrequencies, within which each 
unique word is a key with a value corresponding to the number of times the word was 
encountered in the
"words" array.

The function then loops through the wordFrequences array to find the word
with the highest number of occurrences, comparing each count to the highest

What is scope? Your explanation should include the idea of global vs. local scope.
A: Scope refers to where a variable gets and retains its value and definition. A variable defined within a function only retains its definition and value within that function (and within subfunctions of that function). A variable defined globally is accessible and changeable everywhere, but if a variable with the same name is defined locally within a function, that local variable takes precedence while within that function - and disappears outside the function, while the global variable remains.

Why are global variables avoided?
A: Unexpected results are more likely to happen because a variable such a variable may be used by more than one function, and changing its value from within one function will change it for other functions as well. If that was not the intention, bugs will happen.

A: JavaScript's "use strict" statement causes JavaScript to issue an error any time a variable is not explic
