Imports includes 23 non-default packages.
Importing from so many packages makes the package vulnerable to any of
them becoming unavailable.  Move as many as possible to Suggests and
use conditionally.

  The projections of the HRU and grid shapefiles need to be the same (checked with raster::crs() ), please reproject the shapefiles accordingly.
