dreschpe 0:da1bf437cbc1 5 * A common base class for Text displays

dreschpe 0:da1bf437cbc1 8 * at a location), rows and columns (number of rows/cols) functions.
dreschpe 0:da1bf437cbc1 9 * Everything else (locate, printf, putc, cls) will come for free
dreschpe 0:da1bf437cbc1 10 *
dreschpe 0:da1bf437cbc1 11 * The model is the display will wrap at the right and bottom, so you can

dreschpe 0:da1bf437cbc1 13 * maintained internally to the class to make this easy
