/**
* Generate a new string that will support two line text depending on the current string.
* This method calculates the limited width of a text view and creates a string to fit as
* many words as it can until the limit is reached. Once the limit is reached, we decide to
* either return the original title or continue on a new line. How to get the new string is by
* iterating through the list of break points and determining if the strings between the break
* points can fit within the line it is in.
* Example assuming each character takes up one spot:
* title = "Battery Stats", breakpoint = [6], stringPtr = 0, limitedWidth = 7
* We get the current word -> from sublist(0, breakpoint[i]+1) so sublist (0,7) -> Battery,
* now stringPtr = 7 then from sublist(7) the current string is " Stats" and the runningWidth
* at this point exceeds limitedWidth and so we put " Stats" onto the next line (after checking
* if the first char is a SPACE, we trim to append "Stats". So resulting string would be
* "Battery\nStats"
