* Function: test_stats_collection()

* Purpose: Tests verifying correct collection of statistics

*
* Any data mis-matches or failures reported by the HDF5

*
* Return: 0 if test is successful
* 1 if test fails
*
* Programmer: unknown
* ?? / ?? / ??
*
* Changes: Added the base_raw_cnt and base_meta_cnt fields and
* supporting code. This allows the test to adjust to the
* number of page buffer pages accessed during file open /
* create.
*
* The tests for the values of base_raw_cnt and base_meta_cnt

* behavior. Assuming any such change is not indicative of
