Toolkit to produce a fancy console output (boxes, tables, charts, colors).

// A table definition matrix should define the following properties:
//   - 't': top row (3 symbols),
//   - 'm': middle row (3 symbols),
//   - 'b': bottom row (3 symbols),
//   - 'v': vertical separators (3 symbols) - left border, internal, right border,
//   - 'h': horizontal separators (3 symbol) - top border, internal, bottom border,
//   - 'w': (optional) width of individual t/m/b/v symbols.
// t/m/b/v lines should have the same width for each symbol.
// h should have 3 symbols of length 1.

// The default value for 'w': 1
