Cluster analysis of advisory fetched from different DataSource in VulnTotal #822

We would want to have an interactive graph representing the extent to which the different DataSources differ.

• Different attributes will have different weightage
  Ex: wt( diff( fixedversionᵒˢᵛ , fixedversionᵒˢˢ)) > wt( diff(affectedversionsᵒˢᵛ, affectedversionsᵒˢˢ )) > wt( diff(aliasesᵒˢᵛ, aliasesᵒˢˢ))
• Ideally for a reasonably undisputed security advisory, most data sources should lie in close proximity
