Added arithmetic functions for subtraction, multiplication and division.
Refactored command log handling so that relevant variables and methods all declared within an IIFE closure.
Changed handling of prompts slightly.
Moved update_console function to reside with other console functions.
Added quotation marks as field bounds to separate_terms function.
Separated the formatting of the prompt from the command log.
Outsourced Lisp interpretation functions to separate file and moved scripting in console.html to bottom of document body.
Outsourced styling to CSS file.
Outsourced process loop with dependence on callback and abstracted interpretation script.
