Add more examples + a basic metadata framework (#233)
* Update index.md * Add a histogram example Datashader won't work, but this is a good approximation * Fix link in the rasters example * Enable plotting MultiLineStrings * Update the contour example to show all features * Better theming for contour example * Add the "annotation" and "Hurricane Katrina" examples from Cartopy More to come soon * Bugfixes for docs * Remove individual activations from examples * First foray into example card block * Fully implement the example meta block * Clean up make.jl * add the Cartopy example for Vesta * Fix the projection in is_it_a_plane * Templates for new examples * Change docs to the new way of doing things * Add arrows example * add params and data to vestaa3d * add TopoPlots to docs/Project * Fix errors in the examples * set RDS_PATH in makedocs also * actually deploy docs * add ImageTransformations to the project for `imresize` mainly. * Fix cardmeta blocks not being commented This sounds like a mistake I will keep making :D * Add a streamplot example on geoaxis
