dump data from calmet format 3d met data

Need fortran compiler. Intel and gfortran are known to work on Linux

make This creates executable calmet_dump

calmet_dump calmet.m3d calmet_dump 2, 3 calmet.m3d

The above dumps all variables, all tstep for grid cell (i,j) = (1,1), or (i,j) = (2,3), for example

calmet_dump -

The above commane ('-' as argument) will prompt user for further inputs. it will ask

1. filename
2. idx jdx to extract (default = 1,1)
3. start time to extract, YYYYJJJHH, SSSS (default = 1999010100, 0000, i.e. beg of year 1900)
4. stop time to extract, YYYYJJJHH, SSSS (default = 2099123123, 3599, i.e. end of year 2099)
5. list of values to extract, one value in each line, end with blank line

To got time and variable in the file, i first run with simple run method, write donw what you want to do, and then type (or you can write it down into a text file and redirect into code like calmet_dump - < my_inputs > out.csv)

Example goes like below. I redirected output to go to out.csv. code asks me each input and i have to type each without any error. then i got csv output.

$ ./calmet_dump - > out.csv

Obviously this is not nicest interface. It would probably make more sense to write a code to convert into NetCDF format or something that user can do whatever. But i am OK with this for now.
