[svn-r4733]

Purpose:
	Feature Changes
Description:
	Okay, I needed to add in more parameters so that the user can modify
	how things are supposed to work with the PIO programs. Also needed
	to change the algorithm a bit to make these work. And needed to add
	in timing for the READ option.
Solution:
	Added the above things. The parameters took a major rewrite of the
	command-line parsing stuff. Here's the usage statement:

usage: pio_perf [OPTIONS]
  OPTIONS
     -h, --help                  Print a usage message and exit
     -d N, --num-dsets=N         Number of datasets per file [default:1]
     -f S, --file-size=S         Size of a single file [default: 64M]
     -F N, --num-files=N         Number of files [default: 1]
     -H, --hdf5                  Run HDF5 performance test
     -i, --num-iterations        Number of iterations to perform [default: 1]
     -m, --mpiio                 Run MPI/IO performance test
     -o F, --output=F            Output raw data into file F [default: none]
     -P N, --max-num-processes=N Maximum number of processes to use [default: 1]
     -p N, --min-num-processes=N Minimum number of processes to use [default: 1]
     -r, --raw                   Run raw (UNIX) performance test
     -X S, --max-xfer-size=S     Maximum transfer buffer size [default: 1M]
     -x S, --min-xfer-size=S     Minimum transfer buffer size [default: 1K]

  F - is a filename.
  N - is an integer >=0.
  S - is a size specifier, an integer >=0 followed by a size indicator:

          K - Kilobyte
          M - Megabyte
          G - Gigabyte

      Example: 37M = 37 Megabytes

Platforms tested:
	Linux, but not fully finished...
