/* Function: main
Main entry routine for the benchmark.
This function is responsible for the following steps:
1 - Initialize input seeds from a source that cannot be determined at
compile time. 2 - Initialize memory block for use. 3 - Run and time the
benchmark. 4 - Report results, testing the validity of the output if the
seeds are known.
Arguments:
1 - first seed : Any value
2 - second seed : Must be identical to first for iterations to be
identical 3 - third seed : Any value, should be at least an order of
magnitude less then the input size, but bigger then 32. 4 - Iterations :
Special, if set to 0, iterations will be automatically determined such that
the benchmark will run between 10 to 100 secs
