Description

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
