Create Colorization structure to colorize table.

[zhiburt]

See #126 for a picture how output could look like after using the option.

The idea is to create Colorization as structure for table colorization.

table.with(Colorization::new(color1, color2).pattern(ColorizationPattern::Chess))

enum ColorizationPattern {
  Columns,
  Rows,
  Chess,
}
