Title: Display multiple series with different markers

This commit adds the ability to provide multiple series in the format:

``` ruby
>> series = [[0, 3.4, 5.9], [1, 2.5, 4.3], [2, 5.2, 3.5]]
```

The given series will draw the following chart:

``` ruby
>> puts AsciiCharts::Cartesian.new(series, :markers => ['X', '%']).draw

6.0| %
5.5|
5.0| X
4.5| %
4.0|
3.5| X %
3.0|
2.5| X
2.0|
1.5|
1.0|
0.5|
0.0+------------
0 1 2
```

This feature is currently not compatible with the :bar option.
