v4.0.1

WPS Version 4.0.1

This bug-fix release of the WPS addresses one significant issue in metgrid
and several other minor clean-up items.

* The metgrid program now supports the use of input meteorological datasets
  on a rotated latitude-longitude projection that provide a grid-relative
  horizontal wind field. In particular, this allows the WPS to properly use
  NCEP RAP data.

* The default path of the static, geographical datasets has been updated to
  reflect re-organization of the NWSC /glade filesystem. This change should
  only benefit users of NWSC Cheyenne.

* The logic in the configure.wps script has been updated to better locate
  new WRF source code that was obtained either by cloning the WRF GitHub
  repository or by downloading a GitHub archive file.
