[ESIP-CF] UDT's for metadata

[Upendra Dadi]

Hi Ted,
   I did receive your email. Thanks! I agree with you that UDTs could be 
quite useful. Using UDT instead of CF variables like grid_mapping 
variable (we call such variables "container variables") or variables 
like platform/instrument parameters definitely makes things look lot 
more cleaner. One could keep related things together instead of 
splitting data into different variables or metadata into separate 
attributes.
