[svn-r25078] Test program that accepts parameters to control size of Datasets and Maps in container
and times/reports writes / persists / evicts / prefetches / reads.
Reads are of form "rank reads data it wrote", "rank reads data written by next rank" and "rank reads all data"
Reads are done from logged data, prefetched data, or data on DAOS.
Designed to give insights comparing performance of Arrays & KVs
and accessing data in various layers of the storage stack.

+ * h5ff_timings.c: Do some timing of various write / persist / prefetch / read
+ */
+/*
+ *
+ * Creates 3 groups, each with a dataset & a map
+ * In /G-logged, objects will read.
+ * In /G-prefetched, objects will be evicted & prefetched & read & evicted
+ * In /G-stored, objects will be evicted & read
+ * D = dataset; 2d with uint64 datatypes. size is [ (rows_per_rank*#ranks), (cols_per_row) ]
+ * M = map; uint64 keys ranging from 0 to (rows_per_rank*#ranks*cols_per_row)-1
+ * uint64 values, set to same as dset entries
+ * each rank updates "its" dataset entries & map pairs, based on rows_per_rank variable
+ *
+ *
+ * Notes for possible future modifications:
+ * 1) Make Datasets 1D, with entries 2D vectors to mimic ACG Edge List representation
+ * 2) Make Maps have values that are vectors of uint64, to mimic ACG Adjacency list representation (step 1)
+ * 3) Make Maps have values that variable-length vectors of uint64, to mimic ACG Adjaceny list represenations (really)
