Fixed bugs and optimized code

[LarryBattle]

I had some free time during my lunch to look over your code and here's what I fixed.

• Used hash tables instead of Array.prototype.some() for looking up suffix and salutation.
• Created function to convert from lexical to western order
• Used Array.prototype.shift() and Array.prototype.pop() instead of Array.prototype.splice()
• Forced input to .parse() to a string.
• Returns empty object is no input is supplied.
• Bug fix: Trimmed input to avoid creating empty tokens

Example without trimmed input
Input:

whosit.parse(" Larry Battle ")

Returns:

Object {first: "", middle: "Larry", last: "Battle "}

Example with trimmed input
Input:

whosit.parse(" Larry Battle ")

Returns:

Object {first: "Larry", last: "Battle"}
