Subject: [PATCH] Added the ability to morph more than two images

Forgot to replace undefined variable

Removed extra space and added test

Swapped monochrome.png with original.png, it doesn't exist before running tests

Use Array.isArray() instead of instanceof Array

Update morph-more.js

Removed todo comment
