Title: Support for broken-horizontal-bars

This is useful for plotting Gantt charts.

Example:
```
bbh1 = BrokenBarH()
bbh1.y = 3
bbh1.xMins = [2, 8]
bbh1.xWidths = [2, 4]
bbh1.color = "Red"

bbh2 = BrokenBarH()
bbh2.y = 5
bbh2.xMins = [3, 7, 10]
bbh2.xWidths = [2, 1, 4]
bbh2.color = "Blue"

plot = Plot()
plot.add(bbh1)
plot.add(bbh2)
plot.plot()
```
