In SunObject, when deciding if it is day or night, a radiation threshold has been setup instead of just zero. The smet_range script provides more consistent formatting for stations that don't have a given parameter. The IswrAlbedo generator now only uses stations that have HS except if provided with the "FORCE" argument. 

Three serious bugs have been fixed in the SWRad spatial interpolation algorithm: the vector of usable stations is now reset at each timestep, the direct radiation is now properly computed and the julian date for the sun is set in GMT.

A new MOVE directive has been introduce in order to rename meteo parameters. This is processed before any other directive and could be very useful to handle for improperly named parameters (for example coming from GSN).
