Removed unused data set.
Added Value elements for several documentation pages.
Function down_loader() is no longer exported.
Function slippy_cache() is now deprecated, please use ceramic_cache().
New focus on tile-downloading versus tile-loading (as a raster object). The function get_tiles() does nothing but download the tiles. The functions cc_location() and cc_elevation() trigger get_tiles() to download if needed, and then merge tiles into the appropriate raster object.
New function ceramic_cache() to replace deprecated older function.
Function get_api_key() is now exported.
In debug mode the files are only printed, not downloaded. In this case the tile object is returned invisibly.
down_loader() and higher level functions that use it will report on the download task about to occur.
Function get_tiles() will happily download tiles for any source at any zoom for the entire world.
Renamed internal get_loc() function to get_tiles().
Imagery getter functions now accept type = "elevation-tiles-prod" for AWS terrain tiles.
Function cc_location, cc_elevation and friends now allow loc input to be sf, raster, sp types in any projection.
Function cc_location and cc_elevation and friends now allow input of either max_tiles or zoom.
Now aligned to slippymath 0.3.0.
Added function cc_elevation.
Early dev, with Miles McBain at FOSS4G Oceania 2018!
