// Jaden Smith, the son of Will Smith, is the star of films such as The Karate Kid (2010) and After Earth (2013);
// Jaden is also known for some of his philosophy that he delivers via Twitter. When writing on Twitter, he is known
// for almost always capitalizing every word. For simplicity, you'll have to capitalize each word, check out how 
// contractions are expected to be in the example below;
//
// Your task is to convert strings to how they would be written by Jaden Smith. The strings are actual quotes from
// Jaden Smith, but they are not capitalized in the same way he originally typed them;
//
// Example:
//		Not Jaden-Cased: "How can mirrors be real if our eyes aren't real"
//		Jaden-Cased:     "How Can Mirrors Be Real If Our Eyes Aren't Real"
