Implement Histogram and Stacked Histogram

[ctcncgr]

I'm thinking about some more generalized components like histograms and scatterplots.

I think a stacked histogram using D3 would be useful. I will consume this and the lis-simple-table-element component to begin replacing DSCensors multiQC view. The phylotree that is in the works already uses D3 so it will be an existing dependency when that is added.

I'm adding this largely for myself to implement when I get back in November.
