R bindings to theliblwgeom library

This package provides functions that useliblwgeom, includingst_geohash(),st_minimum_bounding_circle(),st_split(),st_subdivide(),st_transform_proj() (transform through proj, omittingGDAL) andst_as_sfc.TWKB() (createssfc fromtinywkb),as well as the geodetic (spherical/ellipsoidal) geometryfunctionsst_geod_area(),st_geod_length(),st_geod_distance(),st_geod_covers(),st_geod_azimuth(),andst_geod_segmentize(). The previously offeredst_make_valid()is now a generic in packagesf (sf::st_make_valid()).

lwgeom depends onsf, whichhas to be installed first. This package uses the liblwgeom library,and compiles a shipped (and modified) version of liblwgeom. It linksto the GEOS and PROJ libraries.

To install from source, it should be enough to have installedsf from source; the resources for this package (PROJ, GEOS)are being reused.

Previous to version 0.1-6,lwgeom would also try to link the systemlibrary liblwgeom; from 0.1-6 on only the shipped version is used.
