Title Case function doesn't accept options and doesn't work for 'UPPER CASE' text

[sirmyron]

Not sure if I'm missing something but I'm trying to normalise imported data that's commonly entered as upper case, but the titleCase function doesn't work for this. I have to first be calling the toLowerCase method on the string which I feel defeats the purpose.

Also, there's no options parameter for me to pass in a transform. Though, I still think I shouldn't need to do this. I figured the aim of this library is to force text of any format into the format of the chosen function. Are my expectations incorrect based on the goal of the library?
