Overview

This class takes in the arguments passed to the liquid tag, and splits it up into ‘words’ (correctly handling quotes and backslash escapes.)

To handle quotes and backslash escaping, we have to parse the string by characters to break it up correctly. I’m sure there’s a library to do this, but it’s not that much code honestly. If this starts getting big, we’ll pull in a new dependency.
