removes rendering functions in favor of a separate package, vegawidget - vegawidget functions imported and exported using templating function vegawidget::use_vegawidget().
adds requirement to use reticulate (>=) 1.9, to avoid conflict between data-frame variable-names and python methods (#50, @aliciaschep) and to remove the need to use the r_to_py() function for data (#83)
updates to use Altair 2.1.0, which offers tooltips (#29, #46, @aliciaschep)

adds function check_altair() to check installed version against supported version (#42, with @aliciaschep)
updates install_altair() (#41)
synchronizes with Altair v2.0.x (#36)
new function to manage installation of Altair Python package: install_altair() (#1)
makes Vega datasets available through import_vega_data() (#25)
significant changes to the rendering function vegalite():
if the embed argument is NULL, vegalite() sets it to getOption("altair.embed_options") - if that is not defined, the vega-embed defaults are used
width and height arguments to vegalite() are used now to specify the total width and height of rendered charts - notes: (1) this is effective only for single-view charts, (2) width and height apply to the chart only, they do not take into account any action-links - if arguments are not set, the size of the chart is determined from the chart specification (#18)
vegalite() strips the style attribute from the <div/> for the htmlwidget - this has the effect of letting the rendered Vega-Lite chart determine the size of its container (#16, #18)
adds concatenation operators for charts: |, &, + (#22, @aliciaschep)
adds function vega_embed(), with friend only_actions(), to support embedding options in vegalite() (#16)
updates css for embedding, makes the action-links look much better (#20, @aliciaschep)
adds tooltip-capability to vegalite() renderer, with functions vega_tooltip(), add_fields(), and friends: vega_tooltip_encoding() and vega_tooltip_all() (#4, with @aliciaschep)
adds a NEWS.md file to track changes to the package
achieves minimal functionality
