Gdal resampling methods

WebOverview of regridding/resampling. @visr @DirkEilander This is a short overview of resampling methods, related to projected and unprojected geospatial grids and meshes. GDAL (and GDAL via rasterio) are probably the most commonly known. Supports a variety of methods, and is suitable for reprojecting from one coordinate system to another as well. WebDetails. This is an R wrapper for the 'gdalwarp' function that is part of the Geospatial Data Abstraction Library (GDAL). It follows the parameter naming conventions of the original function, with some modifications to allow for more R-like parameters.
