v0.3.6: static html export!

Version 0.3.6:

New Features

• Static html export! You can export a static version of the dashboard using the default values
  that you specified in the components or through kwargs with dashboard.to_html().
  • for custom components you need to define your own custom to_html() methods, see the documentation.
• A toggle is added to the dashboard header that allows you to download a static export
  of the current live state of the dashboard.
• adds a new toggle and parameter to the ConfusionmatrixComponent to either average
  the percentage over the entire matrix, over the rows or over the columns.
  Set normalize='all', normalize='true', or normalize='pred'.
• also adds a save_html(filename) method to all ExplainerComponents and ExplainerDashboard
• ExplainerHub adds a new parameter index_to_base_route:
  Dispatches Hub to /base_route/index instead of the default / and /index.
  Useful when the host root is not reserved for the ExplainerHub
