*Changed functions:*

@ncdf_times.R@ -- changed default time from CET to UTC
                  changed input format of reference time to %Y-%m-%d %H:%M:%

@plot_colourbar.R@ -- changed label "sea" to "water".
                      Direction of the axis description now depends on which side the
                      axis is plotted.

@plotmap.R@ -- grid labels can be set on and of for each axis separately.
               New parameter grid.lwd for the line width of the grid.
               Missing reading of attribute earth_radius for multiple_rotated_pole transformation added.
               Distinguish for 3D variables whether the third dimension is time or level

-------------------------

*Removed functions:*
@nc_open.R@ -- is no longer necessary since ncdf4 package (version >= 1.6.1) considers
             _FillValue as attribute holding missing values

@plotmap_rot.R@ -- the new plotmap.R function includes rotated coordinates

*Changed functions:*
@geo2rot.R@ -- calculates the special case pollat=90.,pollon=0.,polgam=0. (i.e. same geographical coordinates)
               now logically (no longer pollat=90.,pollon=180.,polgam=0. or pollat=90.,pollon=0.,polgam=180.
               for geographical coordinates)

@plotmap.R@ -- this function has been re-written and includes (and thus replaces) the former
               plotmap.R and plotmap_rot.R functions. The new function now decides on the
               existance and value of the grid mapping parameter in the netCDF file .
             A new grid mapping for multiple rotated pole has been added.
             A new option is available: "na.col". The colour of undefined grid pixels is defined
               by this option. By default it is transparent.

*New functions:*
@geo2multirot.R@ -- transforms geographical to multiple rotated pole coordinates (usage: geo2multirot)
                  or multiple rotated pole to geographical coordinates (usage: multirot2geo)
