#2638 Exclude the height varable as a vertical variable if height has no dimension

[hsoh-u]

Expected Differences

The variable with the standard name "height" and "air_pressure" is selected as the vertical level variable for NCCF. The sample NetCDF from the user has height variable but not use as the vertical level. Other variable will be selectas as the vertical level variable if the dimension is not 1.

Added a log message with verbose level 5 for the selected coordinate variables.

I will close this and open new one later.
The fix does not work if the height variable is a 1 dimensional variable.

        float percentile(percentile) ;
                percentile:units = "%" ;
                percentile:long_name = "percentile" ;
        float height (height);
                height:units = "m" ;
                height:standard_name = "height" ;
                height:positive = "up" ;
