- not trivial if we deal with 1 string with /ns in
- we have to scan the file for /ns every time we display the blinking cursor
- is easier with vectors?
- the difficulty here is that its messy to remember row/column
- can we even get the height of a string formatted block
- shorter strings make inserting quicker
- could have a single string and maintain a vector representing line breaks- however inserting a char meansn having to manipulate the entire vector
- with a vector of strings and then row/column insertion point its prob better
