New Tabs and Oldest Living Person; revised String Delimiter, Lodash, and Function Decorator

Revised the string delimiter to include a conditional to deal with strings not ending in a delimiter. Also changed it from html to js file. 

Also added the redone version of Decorator Function. I left my (admittedly verbose) annotations in there; if you have a chance to check my thinking, especially lines 18-32, I'd appreciate it. I'll clean it up later.

Lodash: one minor change to remove the .map from the findLiving function.

Tabs: I still want to make it prettier, but I'm pretty proud of the jQuery. (Thanks, Hank, for the help on e.target). 

OldestLivingPerson: I tried doing a little more with objects, but it was slow. This way seemed faster, and (I believe) has an O(n^2).

can you figure out a way to inline this without using `float` ?
