.serializeToObject() - A jQuery plugin for serializing form data to object
// TAKEN FROM: https://stackoverflow.com/a/8407771/165673
// IMPORTANT: This does NOT work with nested 'something[other]' type names.

// - Will also ignore any inputs that don't have a name assigned.
// - Handles jQuery UI datepickers well. Doesn't care what format the datepicker uses.
// It will use whatever date format use pass as an option to .serialize_to_object().
//
// REQUIRES:
