Scatter plots of signals by peak model fit score (delta AIC) and max percentile

[alimanfoo]

Consider adding some interactive scatter plots to the site to provide an overview of signals, where each signal is plotted as a point on a scatter plot, with the peak model fit score as the X axis and the max percentile as the Y axis. Signals with strong evidence on both these scores should then appear in the top right of the plot. If the plot was done with bokeh, hover could be added to each signal similar to the hover currently used in the signal summary plots over the genome, including a preview of the peak data and fit. Also clicking on a signal could link through to the signal page.
