-How to implement a buffer:
-- store buffer as a list (to be filled up with characters)
-- buffer is nonlocal
-- when function is called, add to buffer
-- if buffer.is_full() or char == "\n": output buffer and empty buffer
-
-how do we determine if the buffer is full?
-- it can have an arbitrary length
-- it can have a set length based on a percentage of the width of the window
-- we can store a counter and check how many calls the function has recieved and use an arbitrary amount of calls
-
-oplist:
-- get length
-len(self.buffer)
-- possible to output as a string
-"".join(self.buffer)
-- resettable
-self.buffer.clear()
-- add/append a character
-self.buffer.append(character)
