currently qtexplorer repurposed webcharts widgets such as outlierExplorer and included those widgets as dependencies. Is it possible to point to {safetyCharts} htmlwidgets sources and avoid duplication?

@xni7 - definitely, makes a lot of sense to me. I'll take this one if it's all the same to y'all.
