[gradsusr] Map for WRF native grid

Well, if someone starts to write one, then I think others will follow. I was saying this because it looks that all other softwares are capable doing this (like NCL, Matab). The PDEF option is in that direction (many projections as well). I think this is doable.

Given the (literally) infinite number of possible WRF native map projections (e.g. Lambert conformal with arbitrary standard latitudes other than 30/60 degrees), this is not possible. GrADS maps can only be drawn for a few supported projections ('set mproj' command). You can certainly specify the _data_ projection with great generality (using PDEF statement), but that is separate from the map that GrADS draws when displaying a field.

I tried so hard to find a better solution that can plot the map on WRF's native grid in GrADS. 
I hope someone could solve the problem soon - if the map data is given by GrADS, this should be easier. 

Another solution is to use a shape file, but you have to convert it.
