docs: Checks to see if the character after the current index in a String is an escapable character.
  Meaning the next character is either a quotation character or the escape char and you are inside

  @param nextLine the current line
  @param inQuotes true if the current context is quoted
  @param i        current index in line
  @return true if the following character is a quote
