ucar.nc2.dataset.VariableDS
An wrapper around a Variable, creating an "enhanced" Variable. The original Variable is used for the I/O. There are several distinct uses:
1. 1) handle scale/offset/missing values/enum conversion; this can change DataType and data values
2. 2) container for coordinate system information
3. 3) NcML modifications to underlying Variable
