Handle text with attributes. We‘re a base class: there are different presentation classes (one, for example, uses overstrikes to handle bold and underlining, while another using ANSI escape sequences
| BOLD | = | 1 |
| ITALIC | = | 2 |
| CODE | = | 4 |
| ATTR_MAP | = | { "b" => BOLD, "code" => CODE, "em" => ITALIC, "i" => ITALIC, "tt" => CODE |
overrides base class. Looks for … etc sequences and generates an array of AttrChars. This array is then used as the basis for the split
