PaleoMapR: fossil-corrected paleogeographic maps in a point-and-click editor

Start the editor with run_app(). The first time, pm_setup() downloads the open data sets (PaleoDEMs, PaleoCoastlines, PBDB, Macrostrat, sea level, HadCM3L climate) into a working folder and builds the corrected grids of the Silurian ages. pm_load() gives the functions behind the editor for use in an R script.
