* Purpose: Create a dataset compressed with the deflate filter.
* This program is used to create the test file `tdeflate.h5'
* which has a dataset compressed with the "deflate" I/O filter.
* This dataset will be used to verify the correct behavior of
* the library when a filter is not available for a dataset which
* requires it.
