some pseudocode for the text parsing, lacks linked list entry creation and linking.

TODO:  implement a backspace feature in the text input (make the backspace char somehow remove the last item in the queue, unsure if possible)
TODO:  create linked list header and lib file.  Place in separate file altogether.
TODO:  manage SRAM and boxes for linked list.
