> A netCDF classic or 64-bit offset dataset is stored as a single file comprising two parts:
>  - a header, containing all the information about dimensions, attributes, and variables except for the variable data;
>  - a data part, comprising fixed-size data, containing the data for variables that don't have an unlimited dimension; and variable-size data, containing the data for variables that have an unlimited dimension.
> The NetCDFparser currently extracts the "header part".  
>  -- text extracts file Dimensions and Variables
>  -- metadata extracts Global Attributes
> We want the option to extract the "data part" of NetCDF files.  
> Lets use the NetCDF test file for our dev testing:  tika/tika-parsers/src/test/resources/test-documents/sresa1b_ncar_ccsm3_0_run1_200001.nc
